We used LabVIEW to assign start frequency, final frequency, point of frequency, time delay and show frequency response on front panel. The formula we used in changing frequency 〖10〗^(a+[(〖10〗^b-〖10〗^a)/(N-1)]*i ) a is the start frequency (〖10〗^a), b is the end frequency(〖10〗^b), N is the point we need to plot the frequency respond and i is instantaneous round of the loop in LabVIEW
