| Abstract: | A simple Fourier analysing system of Periodic signals by using ordinary instruments is set up. The frequency and amplitude of the harmonics of square wave are measured, and the fourier expansion of the square wave is easily verified. |
| Keywords: | Fourier series square wave function super heterodyne frequency selector |
