AN2249 - PSoC® 1 Pseudo-Random Sequence Generator User Module as a One-Shot Pulse Width Discriminator and Debouncer
AN2249 describes how to use a Pseudo-random sequence generator (PRS) user module to debounce noisy comparator output signals.Real world signals often cross comparator trip points multiple times as they transition. Most often, these multiple transitions are unwanted. A PRS user module may be configured as a one-shot and used to debounce these signals. An example with multiple implementations is demonstrated.
