What is high pass vs low pass?
A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. A low-pass filter (LPF) attenuates content above a cutoff frequency, allowing lower frequencies to pass through the filter.
How do you know if a circuit is high pass or low pass?
If a filter passes low frequencies and blocks high frequencies, it is called a low-pass filter. If it blocks low frequencies and passes high frequencies, it is a high-pass filter.
What does high pass refer to?
An audio high pass filter (HPF) is an equalization tool that attenuates all frequencies below a set point. In other words, high pass filters remove low frequencies while allowing high frequencies to pass through. They are used in almost every application of audio technology.
How can I convert my low pass to high pass?
Lowpass to Highpass
The lowpass prototype is converted to highpass filter by scaling by 1/s in the transfer function. In practice, this amounts to capacitors becoming inductors with a value 1/C, and inductors becoming capacitors with a value of 1/L for passive designs.
