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.
