How to Regard ADCs and DACs in Circuits
One of the confusing aspects of circuit design involves circuits with multiple representations of variable values. Circuits commonly have both analog and digital components and with analog-to-digital (A/D) converters (ADCs) and D/A converters (DACs), voltages and currents that are functions of time (or waveforms) appear in both analog (continuous) and digital (discrete) representations.
To appreciate the problems that can arise, consider a simple example of an analog and digital (or mixed-signal) system.
