sir in the end of the lecture when you putiing the value of n=4 so that the value of Hd should become to zero........plz clear the doubt sir
for n=4 hd(n) will become 0/0 form. So, to overcome this situation we will use L'Hospital rule and after that we will substitute the value of n=4.
If the sampling frequency of the input signal h(n) is increased, how does it affect the output signal h'(n) ?
