Question 2 (a) In a simple binary ASK digital modulation scheme, the carrier signal is given by: cos(2πfct) The digital information signal being conveyed is represented by a unipolar square wave with amplitude A and frequency $f_o$. Given that the Fourier Series representation of the digital information signal is: $A\left[\frac{1}{2} + \frac{2}{\pi}cos(2\pi f_ot) - \frac{2}{3\pi}cos(6\pi f_ot) + \frac{2}{5\pi}cos(10\pi f_ot) + ...\right]$ Show that the spectrum of the resultant ASK modulated waveform is of the form: $A\left[\frac{1}{2}cos(2\pi f_ct) + \frac{1}{\pi}[cos(2\pi (f_c + f_o)t) + cos(2\pi (f_c - f_o)t)] - \frac{1}{3\pi}[cos(2\pi (f_c + 3f_o)t) + cos(2\pi (f_c - 3f_o)t)] + \frac{1}{5\pi}[cos(2\pi (f_c + 5f_o)t) + cos(2\pi (f_c - 5f_o)t)] + ...\right]$
