There are several ways to evaluate the bandwidth of a signal in the time domain and frequency domain. Previously we looked at the classic relationship of rise time (t r) and bandwidth (f 3db) [Ref 1], ...

Today’s successive-approximation-register (SAR) analog-to-digital converters (ADCs) and sigma-delta ADCs are known for their high resolution and low noise. Nevertheless, achieving signal-to-noise (SNR ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...
