Hi
There is no proplem in the results u get... it is correct and semetrical.
FFT DOES NOT RETURN FREQUENCY FROM 0 TO 2*PI .. BUT FROM 0 TO (63/64) *2*PI with step 2*pi/64.
The first component is the DC and so you will not find it anywhere in the signal.
The spectrum of sampled signal is...
Re: convolution
In LTI systems the output is the convolution between the input signal and system impulse responce.
In DSP LTI systems like filters could be designed in time-domain by designing impulse responce and signal processing will take action by convoluting this impulse signal with the...
