Signal Processing is the art of transforming different kinds of signal (sounds, images, videos, etc.) into a lattice of information that can extracted and applied in many different ways. Digital signal processing (DSP) considers both technological aspects, such as the study of algorithms, and conceptual aspects; it makes the virtual world closer to the physical world. It is used to transform data into useful information for state-of-the-art machine learning models, a growing area for many businesses for decision support and predictive analytics. This work is made possible by DSP Engineers that know how to capture and process signals from both physical and virtual sources.
Signal Processing Engineers are experts in both the technology and algorithms that enable data analysis. They are able to program efficient applications for sensory processing as well as devise effective strategies for storage repository of data. Furthermore, they streamline complicated engineering processes within organizations such as creating mathematical modeling systems or addressing specific modelling problems with meaningful input-output relationships related to their areas of expertise: electroencephalogram (EEG), electrocardiogram (ECG), medical devices and development.
Here's some projects our expert DSP Engineer made real:
- Improving accuracy of machine learning models by fine tuning signal processing code written in C++
- Utilizing Transformers for EEG-based motor imagery recognition
- Analyzing signals and performing Fourier Transform routines in MATLAB/Octave/SCILAB
- Developing Bandpass filters in C++ for data clustering
- Remote debugging using matlab for eeg signal processing
- Extracting features from EEG signals to detect emotion synchronization between a mother and an infant
- Cleaning Time Series Data with columnwise smoothing in Python Panda
Indeed, Signal Processing has been integral in speeding up key engineering projects that require complex mathematical modeling processes to be completed. Our expert DSP Engineers on Freelancer.com are here to assist you with your project no matter the scope. So if you need help with a Signal Processing problem or want advice on improving existing strategies within your organization, you can trust these professionals provide expert advice and results quickly and cost-efficiently.

Analog Radio Transmitter Specialist
5 дні(-в) left
I run an analog broadcasting facility and need an experienced radio engineer to work directly on our transmitter and tower-mounted antenna system. Your focus will be the RF chain—from the exciter right through to the radiating elements—making sure we’re operating at peak efficiency and fully within our licensed technical limits. You’ll have access to current schematics, field strength and SWR readings, plus any service manuals we hold. Using your own measurement gear (spectrum analyser, dummy load, vector VSWR meter, etc.) or equivalent tools on-site, I’d like you to: • Diagnose and resolve any signal quality or coverage issues linked to the transmitter or antenna • Retune, align and verify power output and reflected power figures • Docu...

433 MHz PCB Pre-Compliance Review
3 дні(-в) left
Верифіковано
I have a compact 433 MHz transmitter built around a CMT2219B RF module driven by a GD32E230G8 MCU. Before we invest in the formal lab work, I want an experienced RF-compliance engineer to look over the current schematic and two-layer PCB layout to maximise our chances of passing both FCC Part 15 and the equivalent ISED requirements. The focus is squarely on RF performance. I have no existing test data, so I’m relying on your insight to flag anything that might push us over the limits once we reach conducted or radiated emissions testing. Key areas include the matching network around the module, antenna feed, ground strategy, return-loss considerations, filtering, and any layout tweaks that could shave a few dB off leakage. You’ll receive the design files (Gerber, pick-and-pla...

Modular Conductivity Tester based on Eddy current

Верифіковано
I need a compact, modular eddy-current device built from the ground up to verify the purity of non-ferrous metals during material research and development. Because the unit will often be carried to mines, scrapyards, and temporary field labs, I’m prioritising a rugged, weather-resistant enclosure, battery operation for a full working day, and quick-swap probes so I can tailor frequency and coil geometry to different sample shapes. Core expectations • A handheld main unit that houses the signal generator, receiver, display, data-logging memory and rechargeable power pack. • Interchangeable probe modules covering the typical kilohertz-to-megahertz range used for non-ferrous purity checks, each probe auto-calibrating on connection. • On-board firmware that shows im...

Comprehensive PSK Circuit Simulation
1 день left
I need a complete phase-shift keying (PSK) circuit designed, simulated, and documented. The task starts with drawing a clean, logically laid-out schematic, then moves on to running a thorough simulation that verifies modulation and demodulation performance under realistic conditions. I have a template circuit but it needs formatting to the correct pins. You are free to pick the tool you know best—LTspice, Multisim, MATLAB/Simulink, or any other platform that can deliver trustworthy waveforms and numeric data—as long as the final results are reproducible on my end. What I expect in the hand-over: • A clearly annotated circuit diagram showing every component value and reference designator. • Simulation files plus screenshots or plots of key signals (carrier, mod...
