Signal Sampling Problem

Hi! Good morning, can someone help me to solve this following sampling excercise?

  1. A digital communication link carries binary-coded words representing samples of an input signal

Xa (t) = 3 cos 600πT + 2 cos 1800 πT

The link is operated at 10000 bits/s and each input sample is quantized into 1024 different voltage levels.

  1. What is the sampling frequency and the folding frequency?
  2. What is the Nyquist rate for the signal Xa (t)?
  3. What are the frequencies in the resulting discrete-time signal X(n)
  4. What is the resolution Δ?

Thank you so much in Advance!

    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...
