Signal Processing Jobs

Need PHD guidance for student of VLSi on Optimization of Hetro junction Tunnel field effect Transistor for nano VLSI applications. From identifying Research Gap to final results. Work to be carried out in Silvaco Tcad

I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. Delive...

I am building a free-space optical communications platform and need a complete pointing, acquisition, and tracking software package that can consistently maintain sub-degree alignment between my optical terminal and a remote node. Core expectations • Pointing accuracy: better than 0.5° under nominal environmental conditions; 100% uptime once locked. • Communications interface: native Ethernet/IP for command, telemetry, and reporting status. • Platform: x86/Linux preferred; however, I can compile on other POSIX systems if the code is portable. Your solution should include: 1. Real-time control loop that accepts attitude sensor data (e.g., IMU, encoders) and drives two-axis galvanometers and a MEMs array. 2. Acquisition logic capable of coarse scan, fine sc...

I have an ultrafast-laser–written waveguide already modelled in RSoft (the .dat structure file is ready), yet every attempt to launch light through it in BeamPROP ends with complete loss of signal. I need an RSoft specialist who can open my file, set up the correct input field and boundary conditions, run the propagation and show where the power is disappearing. Your task will be to: • Configure the launch conditions so the field actually couples into the guide. • Optimise any parameters necessary in geometry or materials to remove the loss of signal (mode mismatch or other distortion could be contributing). • Deliver screenshots, the corrected RSoft project file and a brief note explaining what you changed so I can reproduce the result. When you reply, focus...

I need a freelancer to help locate the source of radio signal interference in an urban environment. Requirements: - Use triangulation techniques to pinpoint interference source - Work in complex urban settings with potential obstructions - Provide detailed reports on findings Ideal Skills: - Experience with radio frequency (RF) technology - Familiarity with urban signal behavior - Strong analytical and reporting skills

I need robust, well-documented firmware that lets an ESP8266 on the Arduino platform both send and receive infrared commands for multiple air-conditioner remotes. Serial command-line interaction over USB or Telnet is all that’s required; no web or mobile interface is necessary. Core tasks • Build or adapt an Arduino-compatible sketch that scans incoming IR frames, decodes them, and logs the raw timing as well as the decoded protocol and data. • Implement a complementary routine that allows me to replay captured frames or craft new ones from the command line, then transmit them through an IR LED with correct carrier frequency and timing precision. • Structure the code so adding or tweaking protocols is straightforward—I will be experimenting with a variet...

Description I am looking for someone experienced in EEG data analysis using MATLAB and FieldTrip to provide analysis support for a university research project investigating the effects of attentional load on multisensory integration (MSI). I have already completed data collection and have the raw EEG data in BrainVision format (.eeg, .vhdr and .vmrk) for multiple participants. The experiment includes auditory (A), visual (V) and audiovisual/bimodal (AV) stimuli. Participants also completed an N-back manipulation involving 0-back, 1-back and 2-back conditions, which is being used to manipulate attentional/cognitive load. The overall aim is to investigate whether multisensory processing/integration changes depending on attentional load, using behavioural and EEG measures. I am looking f...

I need a MATLAB expert to analyze EEG data from a research experiment. Key requirements include: - Experience with various EEG analysis techniques, especially ERP, frequency, or connectivity analysis. - Proficiency in EEG signal preprocessing like filtering, artifact removal, normalization, and epoch extraction. - Ability to handle and interpret complex datasets. - Strong background in neuroscience or related fields is a plus. Please provide detailed analysis methods and tools you plan to use in your bid.

$10-$40 Max for completed project This Bridge is already smart: just needs formatting and adaptation to Polymarket: Specialist Needed: Transform Existing Quant Bridge Into a Native Polymarket Data-Analysis & Decision-Execution Engine I have an existing quantitative trading framework called Quant Bridge that was originally designed for trading analysis. I want to explore a fundamentally different application of it: I want to transform Quant Bridge into a dedicated Polymarket Data-Analysis & Decision-Execution Engine. IMPORTANT — THIS IS NOT A COPY-TRADING BOT PROJECT I already have a separate Polymarket copy-trading bot that follows a highly ranked wallet and performs additional consensus analysis. I do NOT want you to take that bot and simply add Quant Bridge functionality...

Project Brief: ESP32-P4 + ESP32-C6 HDMI CEC & IR Controller Board 1. Project Overview Seeking an experienced PCB designer to create a custom, compact controller board designed to manage media devices via HDMI CEC and external Infrared (IR). The architecture relies on a dual-MCU setup: an ESP32-P4 acting as the primary application processor (handling HDMI protocols and IO) and an ESP32-C6 serving as the wireless (Wi-Fi/BLE) network co-processor. 2. Core Processing & Architecture * Main Application Processor: ESP32-P4. * Network Co-processor: ESP32-C6. * Interconnect: Implement a high-speed communication bus (e.g., SDIO or SPI) between the P4 and C6 for network bridging. * Debugging (Optional but recommended): Expose standard JTAG test points or a micro-header for both MCUs to...

I have a pair of Diamond-series Wharfedale speakers that I’d like professionally wired to my stereo receiver. The job is straightforward: supply or recommend the correct gauge speaker cable, make clean, secure terminations (banana plugs or bare-wire binding posts—whichever you think gives the best performance), then connect each channel to the receiver and confirm both speakers are playing evenly with no hum or phase issues. I’m not looking for placement advice—just a neat, reliable wired hookup that lets me power up and listen right away.

I need a complete schematic for an analog circuit that will be used in a signal-processing application. My focus right now is solely on the schematic stage—no board layout or routing is required at this point. You will start from a functional description that I will provide (target bandwidth, expected input/output levels, and available supply rails) and turn it into a clean, well-documented schematic that can later be handed off for PCB layout. Proper component selection, clear annotation, and ready-to-simulate design files are essential. Please work in a mainstream CAD tool such as Altium Designer, KiCad, or OrCAD—let me know which one you prefer so I can confirm compatibility. The final hand-over should include: • The editable source file in the chosen CAD format...
