The high pass filter can be used to filter out undesired low frequencies.
|•||Gain K: The filter gain K determines the high frequency gain of the filter.|
|•||Frequency f: The filter roll off stops at frequency f in Hz. Higher frequencies will pass the filter, lower frequencies will be filtered out.|
|•||Quality Q: The filter quality indicates how steep the phase response will increase up to the frequency f. A quality Q > 0.707 results in a peak in the magnitude response at frequency f.|
Transfer function of the filter:
