The results are shown in the figure below. v(2) is the equal to the transmitted signal, and v(6) is the amplified receiver signal. The blue signal v(9) is the output beat signal, which has a measured period of 1μs. Therefore, f<sub>b</sub> = 1MHz. Â Â As you can see from the figure, the voltage signal v(7) at the output of the peak detector (plotted in dark blue) is a good reconstructed replica of the baseband 300MHz sinusoidal signal. Compare this signal to the envelope of the input AM-modulated signal plotted in yellow. You can use the "Delta Line Mode" of the graph window to measure the period or clock rate of the binary output, which is about 3.34ns consistent with the signal frequency of fs = 300MHz.
