Consider a square-law detector, using a nonlinear device whose transfer characteristic is defined by vz(1) = a,v (1) + azvi(1) where a, and a, are constants, v(1) is the input, and v(1) is the output. The input consists of the AM wave vi(1) = A,[1 + k,m(1)cos(27f.1) (a) Evaluate the output v½(1). (b) Find the conditions for which the message signal m(t) may be recovered from v2(1).

3. Consider a square-law detector, using a nonlinear device whose transfer characteristic is defined by v2(1) = ajv (1) + azv(1) where a, and az are constants, v,(1) is the input, and v2(t) is the output. The input consists of the AM wave vi(t) = A.[1 + kam(t)]cos(2rf.t) (a) Evaluate the output v2(1). (b) Find the conditions for which the message signal m(1) may be recovered from v2(1).
