Waves 16 R2r 2021 (2025)

1. The Core Concept: From Digital to Analog Waveforms An R-2R ladder is a simple, yet incredibly precise, method of converting a digital number (bits) into an analog voltage (a level). When you rapidly feed a sequence of digital numbers representing a sine wave’s amplitude over time into an R-2R network, the output produces a staircase approximation of that sine wave.
