Usually sine wave inverters are more expensive then modified sine wave generators due to the added circuitry. This cost, however, is made up for in its ability to provide power to all AC electronic devices, allow Many engineering tools will assist with this decision, but here we chose to utilize MatLab.In this problem, we want to study the effect of an averaging filter (averaging window) on eliminating the noise on a signal. Use MATLAB to generate a 10 periods of a discrete sin wave signal with amplitude=1 and period = 50 samples. Then add Gaussian noise to it with amplitude 0.1. Pass the noisy signal on an averaging filter of variable length.
Generate white Gaussian noise addition results using a RandStream object and the reset object function. Specify the power of X to be 0 dBW, add noise to produce an SNR of 10 dB, and utilize a local random stream. The sine pulse generator and Gaussian pulse generator blocks are almost identical. The main difference is the shape of the pulse generated. All of the properties that can be changed of the 2 blocks are exactly the same except in the Gaussian pulse generator you have the option to change the order of the Gaussian function.
