A Power Monitor with Improved Response Time
By: Michael Harney, Signal Display Systems
A selective sampler enables you to sample a signal more quickly and efficiently while retaining the desired frequency resolution. The technique can be used to detect transient power changes rapidly, before blackouts occur. more >>
