DSP Engineer - C Programming (1-10 yrs)

Job Description :

We are seeking a highly skilled developer with expertise in digital signal processing to design, develop, and implement an optimized digital filter in C. The ideal candidate should have a strong background in algorithm development, digital filter design, and embedded systems, with experience in creating efficient and high-performance solutions.

Responsibilities :

- Design and implement an optimized digital filter algorithm in C to meet the specified requirements.

- Develop the algorithm to handle signal ranges from 0.25 Hz to 7 MHz.

- Ensure the frequency response achieves zero outside the specified variable cutoff frequency during each epoch or loop execution.

- Create a solution without relying on external or proprietary library functions.

- Maintain optimal cycle and floating-point accuracy for real-time applications.

Key Features to Implement :

Low-Pass Filter Design :

- Achieve near-unity gain in the passband.

- Ensure the stopband gain is close to zero.

Band-Pass Filter :

- Initially implement a Butterworth filter up to the 10th order.

- Ensure near-unity gain in the passband and stopband gain close to zero.

Qualifications :

- BE/BTech or ME/MTech

- Strong proficiency in C programming, especially in algorithm development for digital signal processing.

- Experience with digital filter design, including low-pass and band-pass filters.

- Familiarity with Butterworth filters design and implementation.

- Expertise in optimizing code for cycle and floating-point accuracy.

- Ability to work independently without external libraries.

Preferred Skills :

- Prior minimum 2 years' experience in real-time signal processing applications.

- Understanding of frequency domain transforms (e.g., FFT, wavelets).

- Experience with embedded systems or DSP platforms.
