WHAT IS THE PROPERTY OF DFT
Analog to digital conversion
The interface between an analog signal and a digital processor is
DFT AND IDFT
FFT may be used to calculate
Even and odd samples
DIT algorithm divides the sequence into
2Log2 N stages
The computational procedure for Decimation in frequency algorithm takes
Digital signals
Telegraph signals are examples of
Digital to analog conversion
The speech signal is obtained after
1)Relates the conditions in time domain and frequency domain
2) Helps in quantization
3) Limits the bandwidth requirement
The Nyquist theorem for sampling
1)Samples of a continuous signal
2) A time series which is a domain of integers
3) Time series of sequence of quantities
A discrete time signal may be
δ(n) = 1, n = 0
= 0, n ≠ 1
The discrete impulse function is defined by
