DSPP Experiment No. 2 - Discrete Fourier Transform

The aim which has to be achieved and the contents of this experiments are as follows :
 Discrete Fourier Transform and Inverse Discrete Fourier Transform
We have performed using C.
On analysis we saw, as number of values were increased in case II the quality of spectrum is IMPROVED.  One important factor is of the magnitude spectrum of the output which is obtained by Discrete Fourier Transform. Two cases with input signals are taken.
we concluded that 
- As N increases :
   - frequency spacing reduces
   - Approximation error in representation of spectrum decreases
   - Resolution Increases

Also one important factor noticed is that, The visual Apperance of Signal (Quality) INCREASES !

  2. The DFT is also used to efficiently solve partial differential equations, and to perform other operations such as convolutions or multiplying large integers.
