Fourier Analysis Kit


In electronics, we come across complex signals. They consist of  pure sine  and consign waves. The mathematical tool that helps us  in the analysis of complex signals is called the Fourier Theorem. According to this theorem, a square wave consists of the fundamental and other odd harmonics. Similarly, a clipped sine wave consists of the fundamental and other even harmonics.
The above results have remained only a theoretical exercise till now. We have now designed a kit that can be used to analyses any complex wave (square, clipped sine wave, triangular wave etc). It enables one to verify the existence of different harmonics  and measure their relative amplitude. 
The kit consists of a stabilized power supply unit (6-0-6), a function generator  and the analyser. The function generator and the  analyser are housed in metal cabinet. Square, triangular and clipped sine wave form are generated by a specially designed integrated circuit function generator whose output frequency  can  be varied in the range of 500Hz to 15KHz. The output level of the sine and  triangular waves can be varied using the amplitude potentiometer provided on the front panel of the main unit. The frequency of the generator is displayed on six digit frequency counter (built in).
The only equipment needed for the experiment is a CRO any low cost CRO will serve the purpose.
