I need solve this
1. if a signal s(t) has the following specification s(t) = 13 sin (2000nt + π) for binary 1 s(t) = 5 sin (2000t+) for binary 0 What kind of modulation is applied? Why? 2. Draw the modulated signal for the following digital signal if we apply a phase shift keying using the following carrier s(t) = sin (6πt + π) for binary 1 s(t) = sin (6πt + π/2) for binary 0 1v Ov Input binary sequence 3. If an audio signal has a bandwidth equal to 30 KHz, what will be the bandwidth of the AM modulated signal?
