Abstract: An experiment in transmitting speech by Pulse Code Modulation, or PCM, is described in this paper. Each sample amplitude of a pulse amplitude modulation or PAM signal is transmitted by a ...

Differential pulse code modulation (DPCM) and predictive quantizing are two names for a technique used to encode analog signals into digital pulses suitable for transmission over binary channels. It ...

MATLAB PCM System Simulator demonstrating digital signal processing fundamentals. Features sampling, quantization (uniform/μ-law), multiple encoding schemes, and signal reconstruction. Includes ...

Frequency-modulated continuous wave (FMCW ... the A121 can also monitor vital life signs such as breathing and pulse rate. As the sensor outputs phase and amplitude of the received signal, it’s ...
