Generate an analog signal using the following equation ,
Signal = 2*sin(2*pi*20*t)+0.4*cos(2*pi*100*t)+0.1*sin(2*pi*500*t)+0.05*randn(size(t));
. Show the signal in time and frequency domain and calculate the capacity using Shannon capacity formula .
• Show the quantize signal considering 6 equally distributed levels and provide image for one cycle of the original signal and quantized signal ( using subplot ) .
