When filtering an audio signal, what frequencies must bepreserved? First determine the frequency range produced by thehuman voice, and the audible range of the human ear.2. For pulse oximeter signals for heart rates less than 240 beatsper minute, what do you expect will be the important spectral andother signal characteristics that need to be preserved in

As expected, most of the energy of the signal, in this case the bird's high frequency voice, is concentrated in the frequency band of around 2000 - 6000 Hz. To filter this out, we can apply a low-pass filter with a cutoff …

The bandpass function has two outputs. The first one is the filtered signal (of the input signal), and the second one (the ‘d’ output) is a digital filter object. Once you provide the necessary frequency, (and if you desire, name-value pair) arguments to the bandpass function, it will provide you with the filtered signal and the filter it designed. . Use the second output with …
