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. Sketch what you would expect to see on the oscilloscope for an ideal system (an ideal system is noiseless and jitter free) Logic 1 3 volts Time 0 Ть Logic 0 0 Ть Time -2 voltsarrow_forward4. (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.
