Question

3.2.1 A 10-MHz clock oscillator transitioning from 0 to 5 V with rise/falltimes of 20 ns and a 50% duty cycle is connected to a gate as shown in Fig. P3.2.1. A filter is connected as shown. Determine the level of the 11th harmonic at the gate terminals. Obtain these by using the exact expression and by using the spectral bounds. [73.95 dBmV exact, 78.56 dBmV by interpolation] Use PSPICE to confirm this. [4.981 mV or 73.95 dBmV]
