How to do zero padding for DFT?

The resolution is determined by the number of samples and the sample rate. Pad the DFT out to 2000, or twice the original length of x . With this length, the spacing between DFT bins is F s / 2 0 0 0 = 0 .

What is padding with zeros?

Zero padding is a technique typically employed to make the size of the input sequence equal to a power of two. In zero padding, you add zeros to the end of the input sequence so that the total number of samples is equal to the next higher power of two.

What is the effect of zero padding in frequency domain?

In this case, we can say “zero padding in the frequency domain results in an increased sampling rate in the time domain”.

How are digital filters implemented?

The most straightforward way to implement a digital filter is by convolving the input signal with the digital filter's impulse response. All possible linear filters can be made in this manner. (This should be obvious. If it isn't, you probably don't have the background to understand this section on filter design.
