1 Discrete-Time Fourier Transform (DTFT) - IIT Bombay
www.ee.iitb.ac.in1 Discrete-Time Fourier Transform (DTFT) We have seen some advantages of sampling in the last section. We showed that by choosing the sampling rate wisely, the samples will contain almost all the information about the original continuous time signal. It is very convenient to store and manipulate the samples in devices like computers.
Fourier Transform of continuous and discrete signals
www.complextoreal.comthe Fourier series coefficients (FSC). After we discuss the continuous-time Fourier transform (CTFT), we will then look at the discrete-time Fourier transform (DTFT). We write the Fourier series coefficients of a continuous-time signal once again as 0 1 n T t n x t dt j T Ce (1.3) Where Z n is the n th harmonic or is equal to n times the ...
