Figure (6) illustrates the continuous-time odd periodic signal x(t). This signal is time scaled by 1/3 and then fed to the input of LP, HP, and BP filters. Find the frequencies of the signals that appeared at the output of each filter considering the specifications of the following filters: (a) LPF has f. =2.5 kHz, (b) HPF has f, -5.5 kHz and (c) BPF has f =2.5 kHz and f =5.5 kHz. (Hints: the unit of t in the x-axis is msec and Fourier series expansion of x(t) is carried out up to the 11 harmonic components). Figure (6) x(t) ANN -2 2 3 -4-3
