## Question 1.8

#### A mixer has two inputs, one a square wave data signal with fundamental frequency of 600 Hz, and the other a carrier wave with frequency of 10 MHz. The carrier wave, however, is not a perfect sinusoid, but is partly limiting at the top and bottom of the waveform such that it contains a second harmonic component at a level of one-tenth of the fundamental.
Sketch the output from the mixing process, assuming that the square wave input is limited to the first five non-zero harmonics only.
