(ii) How channel? Q-4 The transfer function H(w) of a low-pass filter of bandwidth B is (5) H(w)-1 for w) B. If the signal applied to the filter is v(t)- 10 exp(-100mt), u(t). where u(t) is the unit step response, determine the value of the bandwidth if only one- third (1/3) of the signal's energy is passed by the filter. Hint: Energy of a signal can be evaluated using Parseval's Theorem You will also need to find the Fourier transform of the signal. Finally, from a table of integrals one finds dx =-tan a 151 0-5 An angle modulated signal is given by sin (2x 10³ t) + 4 sin (4x 10¹ t)).
