Signal Processing Engineer Interview

Dec 8, 2025

Anonymous Interview Candidate

No offer

Positive experience

Easy interview

Application

I applied through college or university. The process took 1 day. I interviewed at Texas Instruments (Bengaluru) in Dec 2025

Interview

Briefly scanned my resume for projects relevant to signal processing and then proceeded to give me 3-4 questions related to Fourier Transform, Discrete Fourier Transform, and BPSK. When stuck, hints were given. They were looking for a clear thinking process and familiarity with the basic formulas required for signal processing and communication systems.

Interview questions [3]

Question 1

Given the frequency spectrum of a certain signal that looked like two square pulses centred at +- 100Mhz with bandwidth 5Mhz, what does the time-domain signal look like? Also is the time domain signal real or not?

1 Answer

Question 2

A certain device is capable of computing the DFT of a 512 length sequence. Can we use this device to compute the DFT of a 256 length sequence? How?

1 Answer

Question 3

Either a +1 or a -1 symbol is transmitted with equal probabiility. At the receivers side, some gaussian noise with variance sigma^2 is added. What is the optimal decision boundary? Derive it rigorously for the case when -1 is transmitted with probability 0.75 and +1 with probability 0.25.
