The representation of a p(t) signal in the frequency spectrum that we want to exemplify is...
19. Suppose that we wish to create a signal x(t) = cos(2π10%) sin(100nt) 100Tt (f Suppose that x(t) is sampled with sampling rate 3f. Sketch the spectrum of x(e ) (g) Suppose that we want to generate x(t using a discrete-to continuous converter operating at two times the Nyquist rate. What function xnl do you need to input into the discrete-to-continuous converter to generate x(t)?

can someone help me do this and maybe also the picture of the
scope explain how you get it. thankyou!
Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...
