Create a simple low-pass filter consisting of 10 1's in a row

lpf = ones(1,10)

Plot the spectrum of the signal using the command:

plot(abs(fft([lpf zeros(1,246)])));

Indicate the frequency of the first zero in the frequency response in terms of the sampling frequency (frequency(bin#) = (bin#-1)*fs/(N_bins)
