Figure 5

Peakedness of the instantaneous total power as a function of frequency for the example used in Figure 4. Upper panel shows peakedness in dBc of the instantaneous total power response of a quadrature receiver as a function of frequency. The horizontal dashed line corresponds to the peakedness of a Gaussian distribution. The lower panel shows the total excess (solid line) and average (dashed line) power in the receiver versus frequency. The transmitted signal is a 2-GHz carrier amplitude-modulated by a random 10 Mbit/s bit stream. The impulse response w(t) of the receiver and the pulse shaping of the modulating signal are as in the example shown in Figure 4.
