Filtering for an electronic oscillator From Figure 4.5, we see that a sinusoid of frequency ω0 is present in a square wave. Hence, in the oscillator, we must remove (filter out) the frequencies at 3ω0, 5ω0, and so on, to produce a sinusoid of frequency of wo The electronic oscillator can be depicted by the system of Figure 4.7. The input signal to the filter is a square wave, and its output signal is a sinusoid of the same frequency....
