The output voltage is 63.3% of its maximum at the critical frequencies.
In an RC high-pass filter, the output is taken across the resistor and the output leads the input.
Critical frequencies are also called –3 dB frequencies.
The roll-off rate of a basic RC or RL filter is 20 dB per decade.
In an RL high-pass filter, the output is taken across the inductor and the output leads the input.
