Another design function for optimal equiripple filters is firgr. It also attenuates those signals whose frequency is higher than the cutoff frequency. A lowpass filter is a filter that allows signals below a cutoff frequency known as the passband and attenuates signals above the cutoff frequency known as the stopband. This example shows how to design filters given customized magnitude and phase specifications. Opposite in nature to a highpass filter, a lowpass filter is a filter that allows signals with a frequency lower than the cutoff frequency the frequency at which the output voltage is 70.
