Question 1: Explain the advantage and disadvantage of ASK modulation.

Question 2: A binary data with 100 bps rate is once modulated on ASK, once on PSK and once on FSK. Explain which modulation demands more RF bandwidth.

Question 3: What are advantage and disadvantage of DPSK over PSK?

Question 4: Compare the delay type in DPSK modulator and demodulator. For which one you may use digital device and for which one you have to use analog device.

Question 5: What are the advantages of GMSK over FSK and what real-life communication system uses this modulation?
