This paper describes a pulse code modulation (PCM) encoder that employs a delta modulator as the analog-to-digital converter. A tapped binary shift register and an up-down counter cause delta ...

In this paper, we analyze the inconsistency of mathematical expressions between continuous and discrete phase modulation in the intra-pulse of pulse radar. By referring to the research method of ...

Quantum-ready standards, field-proven SDR attacks, and new P25 link-layer tools are redefining secure RF design. Yesterday’s ...
