Signal Chain Basics #160: Making sense of coherent and noncoherent sampling in data-converter testing

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

Fast ADC Facilitates Direct RF Sampling at Higher Frequencies

The critical component in all digital communications receivers is the analog-to-digital converter (ADC). The ADC sampling rate, bandwidth, and noise tolerance establishes the specifications and ...

Basics of ADCs and DACs, part 1

A block diagram of a typical sampled data DSP system is shown in Figure 2-1. Prior to the actual analog-to-digital conversion, the analog signal usually passes through some sort of signal conditioning ...

A View of Undersampling

Analog measurement resources in today’s mixed-signal ATE use ADCs, and the test methodologies are based on DSP. Two types of measurement resources are distinguished by the relationship of the test ...
