In this experiment we used frequency sampling as a way to implement a digital filter.The main idea of the frequency sampling design method is that a desired frequency response can be approximated by sampling at N evenly spaced points.We observed that the no of lobes in the frequency response increases as the order of the filter increases.The filter's response also gets better with an increase in the filter order.

we also use frequency sampling method to design FIR filters like low pass,bypass,high pass,etc.
