Understanding Concepts of DDC, DUC, Sampling Rate, and Data Rate in ADC/DAC

Understanding Concepts of DDC, DUC, Sampling Rate, and Data Rate in ADC/DAC

The sampling rate refers to the speed at which an Analog-to-Digital Converter (ADC) samples the analog input, or the speed at which a Digital-to-Analog Converter (DAC) outputs the analog signal. This rate is typically provided by the external clock rate to these converters. However, modern ADCs and DACs often have an internal Phase-Locked Loop (PLL) … Read more
