Keep high frequency twice the low frequency.Īs we can see in the output, we have obtained the original & filtered signals for our input cos signal along with their spectra.

In the above 2 examples, we used a three-channel signal, in this example, we will use a 2-channel signal and will pass it through a Bandpass filter. The Bandpass filter has removed the frequencies below the low pass frequency and frequencies above the high pass frequency. S = *cos(pi*'.*T) + randn(size(T))/20 Īs we can see in the output, we have obtained the original & filtered signals for our input cos signal along with their spectra. Keep low frequency and high-frequency tone at a level of two times the intermediate tone.In this example, we will create a cos signal which is sampled at 10000Hz for 1 second and will pass it through a Bandpass filter. S = *sin(pi*'.*T) + randn(size(T))/20 Īs we can see in the output, we have obtained the original & filtered signals along with their spectra. Pass the above signal through the bandpass filter by setting the allowed frequencies.Keep low frequency and high frequency tone at a level of three times the intermediate tone.In this example, we will create a sine signal which is sampled at 10000Hz for 1 second and will pass it through a Bandpass filter.

Let us now understand the code of ‘Bandpass filter’ in MATLAB with the help of various examples: Example #1 The 2-element vector ‘fp’ gives the passband frequency F = bandpass (s, fp, Fx) is used to specify that the signal ‘s’ is sampled at a rate ‘Fx’ HZ.

If input ‘s’ is a matrix, the bandpass function will filter each column of ‘s’ independently F = bandpass(s, wp) is used to filter the signal ‘s’ with passband frequency range provided by the 2-element vector ‘wp’.
