An investigation has been made to find the new frequency from a reference frequency such is done for the beneficial of day-to-day rapid increase in the technology and its uses. The effect of such is derived from the comparison of analog circuits and digital circuits to find the better result. A software analysis is also done to verify the result. Mainly for the regular use of wireless technology this work is done and compared for the analysis of better result. Phase lock loop is used to get the better frequency response from the crystal oscillator used as a reference frequency. It is a very essential component for modern technology.

Keywords: Phase lock loop, analog circuits, digital circuits, reference frequency.
