# Compare Ideal vs. Real Filter with an LCR Meter | Workbench Wednesdays #42


Compare the ideal and measured cut-off frequency for a filter with a handheld LCR meter. Unlike a DMM, these meters apply an AC signal (from 100 Hz to 100 kHz) to determine the reactive component of an inductor, capacitor, or resistor. A simple example here is a low-pass filter. See how the ideal and measured cut-off frequency varies. And THEN, see how it compares between a PCB and a Breadboard.
