ECET 310 Week 7 Homework 7_1

Computer Science - General Computer Science

1. For a QPSK system and the given parameters, determine 2. Which system requires the highest Eb/No ratio for a probability of error of 10-7, four-level QAM or 8-PSK system?

3. Determine the minimum bandwidth required to achieve a P(e) of 10-4 for a 16-PSK system operating at 25 Mbps with a carrier-to-noise ratio of 10 dB

4. A PCM-TDM system multiplexes 32 voice channels each with a bandwidth of 0 Khz to 4 KHz. Each sample is encoded with an 8-bit PCM code. UPNRZ encoding is used.

1 . Four frequencies are applied at the input of a non-linear amplifier.

Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics.

2. Find out the frequency components at the output of a resonant-tuned circuit tuned at 1200 KHz with a bandwidth of 15 KHz and connected at the output of a non-linear amplifier (mixer).
