Cut-Off Frequency: Capacitance: 1 µFnFpF Resistance: 1 ΩkΩMΩ RC Low-Pass Filter Interactive Calculator This tool allows you to visualize the frequency response of a first-order passive RC low-pass filter. It shows the magnitude response in decibels (dB) versus the frequency in Hertz (Hz) passing through the filter. A vertical line designates the filter’s cut-off frequency … Continue reading RC Low-Pass Filter Response Interactive Calculator
