I have noticed certain overlap between digital signal processing and quality assurance for jobs that require expertise in evaluating the quality of the transmitted signals on telecommunication systems like VoIP or IPTV. I have two examples:
For me, however, electronics engineer or quality assurance engineer are not terms that describe enough someone who is able to understand ITU-T standards (MOS, PSQM, PEVG, PESQ, POLQA, MUSHRA), quality of experience (QoE), network terminology (packet loss, bit rate, throughput, transmission delay, availability, jitter), DSP techniques (frequency analysis, FIR/IIR, sampling and quantization), and software programming.
Is there another name for this position? Is there a career path defined for someone who aims to work in this industry? Is this job profile something required nowadays by other companies?
PS: I wonder also if an expert like this can also participate in the creation of new algorithms and the evaluation of the quality of the architecture of DSP systems, as described here: https://www.eetimes.com/document.asp?doc_id=1275520
