2) Spectrum analyzer is an essential instrument for measuring a digital signal in any experiment implementation. It is used to measure a digital signal that contains of Fourier series expansion sine and cosine terms to produce the Fourier coefficients foms. Normally, the output voltage amplitude is captured from the instrument which displays the time-domain signal. By using spectrum analyzer, the noise can be easily detected hence it can be eliminated by using Inverse Fourier mathematical form. In the spectrum analyzer, determine the discrete Fourier series as the periodic sequences is detected as expressed below; 2m n+ sin (6n x[n] = cos n+- 2 cos -n+ + 4 sin
