Question

Device A: mean 116, standard deviation 0.5 mmH Device B: mean 111, standard deviation 1.8 mmHo te the better device in terms of () precision error and (ii) bias error, and explain why Question 2: Conditioning Circuits resist are typically accounted for or compensated for in practice. B. i. Derive the complex transfer function H(o) for each of the two circuits shown in Figure 1. o is defined as frequency in rad/s. art from finite open-loop gain, finite input resistance and nonzero output ance, name three nonideal aspects of real op amps and say how they Ch RL UCD 2018/2019 Page 2 of7 nt, in Ch Rh the Figure 1 e% i. What signal processing operation do these circuits perform on the input vs(0)? iii. Taking RL 1.1 k. CL-1.5 μF, R,-300 kn, C.-15,F, calculate the relevant cutoff frequencies of the circuit in Fig 1b (NOT Fig 1a), iv. By substituting into each transfer function a value of frequency ω lying sure 2 roughly midway between the cutoff frequencies, compare the magnitude gain of circuits a and b, and explain the difference. and C. i. Find Vo in the difference amplifier circuit in Figure 2 for each of the two following pairs of input signal values: (a) V1 -2V, V2 5V 35% out ii. Using this information, compute the common-mode rejection ratio (CMRR) of this amplifier. Express your answer in dB. No Figure 2 Page 3 of 7 UGP 2018/2019
