Answer #1

Benefits of PSK over FSK:

PSK is a data modulation technique which transmits the data continiously based on reference signal or data input.

1.The data carried on a radio communication signal is more efficient in PSK than FSK.

2.It has efficient power System and more bandwidth frequency compared to FSK. In FSK has less effiicient in both power and bandwidth.

3.FSK has limitations to use only in low speed modems due to its bitrate. wheras PSK is used in high speed modems.

4.PSK has higher data rate of transmission, this can be achieved using highlevel of PSK suchas QPSK hence it is used in wireless communications.

example: bluetooth,biometric

5.The probability of error is less in PSK .

6.In PSK scheme it is possible to send a signal having more than one digital value.

Suppose you use phase sensitive detection to measure the voltage acrose a temperature sensor, immersed in a bath of water. Suppose you wish to measure every 10 degrees Celsius as you heat the water from 0C to 100C. If the water is heated at one degree per minute, you want the time constant to be small enough to track temperature changes every 10C. A) Determine an appropriate RC time constant which will allow you to track the changes in temperature....

The jewellery industry is undergoing a vast transformation. There has been a shift in the mindset of buyers who prefer branded jewellers over traditional retailers. Thus, there is a need for small retail jewellers to accept the change and think like big corporations. Even luxury jewellery brands need to attract buyers to their stores using different techniques. Another hindrance to the traditional jewellery business is the growing popularity of online jewellery stores. Thus, there is a greater need for jewellery...
