EC8553 DTSP DISCRETE-TIME SIGNAL PROCESSING

1.What is DFT?

It is a finite discrete frequency sequence, which is obtained by sampling one period of fourier transform. Sampling is done at N equally spaced points over the period extending from W=0 to 2n

2.What is DFT of unit impulse (n)?

The DFT of unit impulse (n) is unity

3.State linearity property of DFT ?

DFT of linear combination of two or more signals is equal to the sum of linear co-efficient of DFT of individual signal

4. When a sequence is called circularly even?

The N point discrete time sequence is circularly even if it is symmetric about point on the circle

5. What is the condition of a sequence to be circularly odd?

An N point sequence is called circularly odd it if is anti symmetric about point zero on the circle
