This paper proposes a novel pulse code modulation /frequency modulation (PCM/FM) demodulation method using an efficient recursive algorithm to compute discrete short-time Fourier transform (DSTFT) of ...

The aim of this program is to simulate the Pulse Code Modulation (PCM) process, where an analog message signal is converted into a digital signal through sampling and quantization. import ...

Pulse Code Modulation (PCM) is a method used to digitally represent analog signals. It involves sampling the analog signal at regular intervals, quantizing each sample into a digital value, and then ...

This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design ...
