Question

What are the absolute bandwidths of the signals shown in Problem 2(a) above? Note: Absolute BW-highest frequency component present in a signal). What is the null-null bandwidth of the waveform in Problem 2 part (iv)? What is the 3 dB bandwidth of x(t) 0.5eu(t)? Abo, write down an equation to find the 3 dB bandwidth of a ilter with transfar finction, H(4). 605+1) a) Find the Fourier transforms of the following signals and sketch their magnitude spectrums i) x(t) 12e u(t), i) x(t)-e, i x(t) sin(100xt) 5, iv) x(t) rect(0.2t) b) If X(o) rect(4ω)-2800-5 r), what is its inverse. x(t)? 』← → 4.atw)@eみSb.)
