All signals above selected frequencies appear at the output and a signal below that frequency gets blocked. They are of two types-Active High Pass FilterandPassive High Pass Filter. The frequency response of a high pass filter is shown below. Here, a dotted graph is the ideal high pa...

Specify the desired filter type (low-pass, high-pass, or band-pass) in the constructor, along with the other needed parameters: the number of taps, the transition frequencies, and the sampling frequency of the data you’ll be filtering. Make one call to the class’ filter function,do_...
