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 ...

Abstract: In this letter, a simple method for modulation and demodulation of minimum shift keying (MSK) is proposed. It has a serial structure, and is easier to implement than the conventional ...

Steel Green Manufacturing's Opti-Rate pulse-width modulation (PWM) rate-controlled spray system, developed in conjunction with CapstanAG, was designed to enhance the accuracy and consistency of spray ...

CDMA Code Division Multiple Access ... where the FFT transform is used. 3.2 OFDM modulation and demodulation An OFDM symbol is a mixed-signal of multiple modulated subcarriers, which could be ...
