Signals amd Systems 12. A power signal x(t) with no signal power outside the frequency range- fe/100 < f < fe/100 is multiplied by a carrier cos(2ifct) to form a signal, y, (t).Then y, (t) is multiplied by cos(2Tfet) to form y, (t). Then y,(t) is filtered by anideal lowpass filter whose frequency response is H(f) = 6 rect(f/2fc) to form y f (t).What is the ratio of the signal power in yf (t) to the signal power in x(t) Py,IP;?

Then y, (t) is multiplied by cos(2Tf.t) to form y,(t). Then y, (t) is filtered by an ideal lowpass filter whose frequency response is H(f) = 6 rect(f/2fc) to form yf (t). What is the ratio of the signal power in yf (t) to the signal power in x(t) Py,IP;¿?
