Passband to baseband conversion: Consider the following passband signal,

ypt = V2sine (2t) cos (200mt).

where sinc (t) = / frac{sin (/pi t) }{/pi t} is the sinc function.

(1) What is the carrier frequency of y_{p} (t) ?

(2) What is the absolute passband bandwidth of y_{p} (t) ?

(3) Find the complex baseband equivalent y (t) of y_{p} (t).

(4) What is the absolute bandwidth of y (t) ?
