1. Two identical loudspeakers are driven by the same oscillator at frequency 480 Hz. They are located on the ground a distance of 4.0 m from each other. Starting far from the speakers, a man walks straight toward the right-hand speaker as shown. How many maxima does the man walk through and at what distances from the speaker are the maxima?

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....
