1. The purpose of the Lag Compensator is: I. Improve the study state response of the close system. II. Speed up the transit response. III. All the above. IV. None of the above.  2. In the Lead Compensator:  I. Z > P. II. Z < P. III. Z = P. IV. None of the above.

I need to solve just the question 2.

Question 33 The receiver in the block diagram is not receiving any incoming stations - the complaint is no sound. On the bench, you injected a 1 mV, 50% modulated AM signal at 455 kHz into Point D, resulting in a very loud tone in the speaker. Which of the selections below are true? A B There's probably a short in the antenna. Local Oscillator 455 KHz Intermediate Frequency (IF) Amplifier You should inject audio at Point F to test the audio amplifier. The IF amp, detector, and audio amp are working. ✔ You should inject signal at Point E to see if the trouble is in the detector stage. ✔ You should inject signal at Point B (at the carrier frequency) to test the frequency converter. E Baseband output 해 4 pts

A flow meter has a linear I/O graph. The input ranges from 0 to 10 liters per minute.  The output range is 4 to 20 mA.  Find the following: a. Transmitter gain, H = Cm/C b. Equation for output Cm in terms of input C c. Output Cm when input C = 6 L/min d. Input C when output Cm = 4 mA *** Please answer sub-part "d", as a, b, c have already been answered. Thank you

Explain the difference between correlated and uncorrelated noise with anexample accordingly.

DZMM having a carrier frequency of 630 kHz is modulated by 2.6 kHz audio signal having an amplitude of 37.5 V. What is the amplitude voltage of 630 kHz carrier frequency at 0.35 modulation index? *
