Question: In this problem we wish to study an interesting effect that arises from LO leakage in direct-conversion receivers [20]. Consider the LO leakage in a direct-conversion receiver, V0 cos ωLOt. Suppose this leakage is added to an amplitude-modulated interferer, Vint(t) cos ωintt, and the result experiences third-order nonlinearity in the LNA (or down conversion mixer).

a) Determine the components near the carrier at the LNA output.

(b) Determine the resulting baseband components and whether they corrupt the desired signal.
