An experimental approach is presented for measuring the (root means square) values of the harmonics contained in a periodic signal by using an active bandpass filter. Instead of electronically sweeping the filter center frequency by the input harmonics, the filter center frequency is held constant and the input fundamental frequency is decreased manually, causing each input harmonic to be swept through the bandpass filter response
