c) Figure 2 shows a square wave against time in miliseconds (ms) and its spectrum in Hertz, (Hz). i. ii. iii. wave. Determine the fundamental frequency of the wa [3 Marks] If the signal passes through a low-pass filter of cut-off frequency of 150Hz, sketch the spectrum after filtering process. [5 Marks] If the same wave passes through a band-pass filter of low pass filter of 60Hz and high pass filter of 30Hz, sketch the spectrum and time waveform of the output signal.
