What is representation of discrete-time signal?
The discrete time signals are represented by x(n) where n is the independent variable in time domain.
What is discrete-time signal explain with an example?
A discrete-time signal is a sequence of values that correspond to particular instants in time. The time instants at which the signal is defined are the signal's sample times, and the associated signal values are the signal's samples.
What is spectrum analysis using DFT?
The DFT can thus be used to exactly compute the relative values of the N line spectral components of the DTFT of any periodic discrete-time sequence with an integer-length period. negative frequencies due to the periodicity of the DTFT and the DFT.
What is the discrete Fourier transform sequence values?
In mathematics, the discrete Fourier transform (DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), which is a complex-valued function of frequency.
