A user must know how to compute the measurements of the oscilloscopes, like Maximum Bandwidth, Carrier Frequency, Lower Side Band Frequency and Upper Side Band Frequency of a signal. Another problem in using oscilloscopes is that one must have basic knowledge in reading signals. An average oscilloscope can weigh around 26.3 kg or 58 lb., which is really bulky and very unhandy it has issues when it comes to portability. Although oscilloscopes are very advantageous in constructing electronic circuits, it has its own disadvantages which affect the user. An oscilloscope is a very complex instrument that is used for testing different types of signals. In conducting signal analysis, a time – domain instrument is needed, and an oscilloscope is the best example. Through mathematical signal analysis, the performance of a circuit board can be predicted based on the voltage distribution and the frequency composition of an information signal. CHAPTER I THE PROBLEM AND ITS SETTING Introduction In any type of design involving electronic circuitry especially those with complicated connections, Signal Analysis is very crucial as it determines its functionality and effectiveness.
