Difference between Fourier transform and DTFT
DTFT is Discrete time Fourier transform
In DTFT and Fourier transform we convert a signal from time domain into frequency domain
DO note they may look similar with their names and stuff But they are not the same
This is because Fourier transform can be applied only to a signal which has a well defined period (i.e) It must have a periodicity which is not equal to infinity
Whereas in DTFT we can use it convert any signal whether it is periodic or aperiodic into sine and cosine series
PS: Started a new thread as it is no way related to DSP but must be known to all friends here in CE
