Unformatted text preview: e three possible choices for the nonlinear system: a) Half- wave rectifier (input = x (t ) , output = x (t ) when x (t ) > 0 and = 0 when x (t ) < 0 ). b) Full- wave rectifier (input = x (t ) , output = x (t ) ). c) Limiter (input = x (t ) , output = sgn( x (t ) ) = 1 when x (t ) > 0 and = - 1 when x (t ) < 0 ). Which of these would you choose to use in your frequency multiplier, and why? 2. (This is an old exam problem.) Suppose that we want to design a subheterodyne recever for broadcast AM. T...
