What Is Software Defined Radio (SDR)? A Practical Explainer for Indian Engineering Teams
Software defined radio moves the work of filtering, modulation and demodulation out of fixed hardware and into software running on processors and FPGAs. This explainer from GSAS Micro Systems covers what SDR is, how it differs from a traditional radio, what the signal chain looks like, why the FPGA matters, and how to pick a USRP radio in India.

How to Evaluate a Unit Testing Tool for Embedded Software: A Buyer's Framework for Indian Teams
Unit test tool evaluations rarely fail on features. They fail because the tool c

Is 100% Code Coverage Enough? Statement, Branch, MC/DC and MCC, and What Each One Proves
No. A coverage percentage records which code your tests executed, not whether yo

Automated Mutation Testing for Embedded C: The Question MC/DC Coverage Cannot Answer
Structural coverage tells you a line was executed. It does not tell you that a d
