Question

Two signals with a band limit of 4000 rad/s such as m1(t) and m2(t) are transferred to H(w) as shown below. It is transmitted simultaneously over a channel that has the function below in the picture.

The signal at point C modulates a carrier signal with a frequency wc>10000 rad/s. D The modulated signal at a point is transmitted through the channel whose transfer function is given below:

H(w) = π ((w-40000)/w) + π((w+40000)/w)

According to this; a) Draw the frequency spectrum of the signals at points A, B, C, and D.

b) Two carriers of the modulated signal at point D are suppressed double-sideband amplitude Since it consists of a modulated signal, the minimum required channel bandwidth W is set the value.

c) According to the W value determined in the previous point, the modulated signal at the D point In order to be transmitted on the channel with the H(w) transfer function, the wc frequency value set.
