Broadcasters have a unique opportunity to satisfy consumers’ desire for the highest possible visual quality while continuing ...
Compliant with ATSC A/53, the DRX3931J, an 8VSB and QAM 64/256 demodulator with integrated IF amplifier, measures 7 m x 7 mm in a 48-pin QFN package. It is reportedly the smallest such device on the ...
This project presents a MATLAB-based simulation of an 8-Pulse Amplitude Modulation (8-PAM) communication system using Sigma-Delta modulation and demodulation techniques. The system is modeled ...
Abstract: Low-frequency characteristics serve as primary metrics for evaluating the acoustic performance of modern microspeakers. However, conventional microspeakers exhibit flat low-frequency in-ear ...
Abstract: This chapter describes some digital modulation methods in order of appearance: digital modulation for analog FM systems, spectrum‐efficient digital FM, linear modulation, spread spectrum ...
