2. Using a well-known trigonometric identity involving the product of the sine of an angle and the cosine of another angle, demonstrate that the multiplication of the incoming FM wave s(t) by the locally generated FM wave r(t) produces two components (except for the scaling factor): 1. A high-frequency component, which is defined by the double-frequency term namely, where km is the multiplier gain. 2. A low-frequency component, which is defined by the diference-frequency term namely. kmAcA, sin[i(t) - 2(0)]...
