- i need helppp pleasearrow_forwardsolve and show workarrow_forward2) (15pts) In a PAM baseband digital communication system, an M-ary system has a channel bandwidth of 2 KHz. The channel introduces 10dB of losses and AWGN noise with a power spectral density of 1*10-6 W/Hz. The application requires a bit rate of 4.8 Kbps and BER of less than 10^-6. Estimate the require transmit power.arrow_forward
- i need helppp pleasearrow_forward1) (2pts) If you know you have a bad clock (lots of jitter) and you are not bandwidth constrained, you should: (Circle the correct answer) a) Set the roll off factor to zero b) Set the roll off factor to ½ c) Set the roll off factor to one 2) (2pts) Short answer: Why do we use M-ary modulation? 3) (4 pts) Short answer: The application engineer comes to your desk and says that the error rate is too high and must be reduced for the application to function correctly. The system is battery operated. What do you tell them is the trade- off?arrow_forwardi need helppp pleasearrow_forward
- 5) (20 pts) You are testing a system that has pulse shape shown below for Logic 1 and Logic 0. You are connecting the transmitter to an oscilloscope which is set up to display the resulting eye-diagram of the system.

(20 pts) You are given a channel with the following impulse response. Determine the set of equations that will be used to determine the coefficients of a Zero-Forcing Linear Equalizer. DO NOT SOLVE FOR THE COEFFICIENTS. Just show the set of equation that would be used to solved the coefficients. 0 m≤-31 -0.33 m = -2 .25 m = -1 h(mb) = 1 m = 0 -0.45 m = 1 0.5 m = 2 0 m≥3arrow_forwardI need help understanding part B.

The channel attenuates the power in the signal by 5 dB. The system uses binary PAM baseband digital communication system with the minimum required bandwidth and a roll-off factor of 0.319. a) (10 pts) What is the estimated minimum required signal power (Pt) at the transmitter?arrow_forwardi need helppp pleasearrow_forward
