Find out the transfer function

QUESTION 17 Consider again the control system illustrated in Figure Q16a and Figure Q16b. Assume that C(s)=10. What is the phase margin of the loop transfer function? Express your answer in degrees, but do not type any units, and round to the closest multiple of 15 degrees

The data-input and data-select waveforms in Figure 7 are applied to the multiplexer. Determine the output waveform F in relation to the inputs.

True or False: A Higher sampling frequency results in a more accurate analog signal recreation result.

4. Signal conditioning element basically takes the output of the sensing element and converts it into a form more suitable for further processing, usually in the form of a DC voltage, DC current or variable frequency AC voltage. The output of the sensing element is usually too small to operate an indicator or a recorder. Therefore, it is suitably processed and modified in the signal conditioning element so as to obtain the output in the desired form that is amplify the signal and filtering the unwanted signal. i. Describe the aliasing phenomenon. ii. Suggest a solution to minimize the effect of aliasing.

Give an example of an analogue device that can be used as a phase comparator in a PLL system and explain its operation.

How to tell the difference between a open loop transfer function and closed loop transfer function?

2. Consider Figure 1.a) Find and draw an orthonormal basis function set for the signal set given in Figure1a. Apply Gram-Schmidt orthogonalization procedure and show your calculationsteps. Describe the signals in terms of the orthonormal bases. Draw the signalconstellation diagram.b) For Figure 1b, using the orthonormal basis set you derived in Question 2a, describethe signals in terms of the orthonormal bases. Draw the signal constellationdiagram.c) Combine the signal sets in Questions 2a and 2b. You must add another signal setto this combination, so that sum of all the signals ultimately form an efficient 8-QAM modulation scheme. Find and draw this signal set and also describe them interms of the orthonormal bases.

The shown sampled signal is the output of the ADC of Arduino Uno, calculate: 1- The number of samples (N) that needs to calculate Ts. 2- The normalized values for the shown max and min (normalized to 5 V). 3- The signal frequency if the sampling time of Arduino ADC is: Ts=112usec. 1020 35
