Answer to Problem 1P

The input resistance of the op amp constraints the value of in and the value of in is 0A.

Explanation of Solution

Discussion:

The input resistance of an ideal op amp is infinite, which restricts the current in to enter into op amp. Therefore, the value of input current is 0.

Conclusion:

Thus, the input resistance of the op amp constraints the value of in and the value of in is 0A.

c.

To determine

Mention the parameter that constraints the value of (vpvn) and also mention the value of (vpvn).

Answer to Problem 1P

The open loop voltage gain of the op amp constraints the value of (vpvn) and the value of (vpvn) is 0V.

Explanation of Solution

Discussion:

The open loop voltage gain of an ideal op amp is infinite, which constraints the difference between the voltage appear across the inverting and non-inverting terminal of the op amp to 0 V. Therefore, vpvn=0V.

Conclusion:

Thus, the open loop voltage gain of the op amp constraints the value of (vpvn) and the value of (vpvn) is 0V.

d.

To determine

Find the value of voltage vo in the given circuit using PSpice.

Answer to Problem 1P

The value of voltage vo in the given circuit is 10V.

Explanation of Solution

PSpice design:

Draw the given circuit in PSPICE as shown in Figure 2.

Electric Circuits. (11th Edition), Chapter 5, Problem 1P , additional homework tip  2

Provide the simulation settings as shown in Figure 3 to obtain output parameters.

Electric Circuits. (11th Edition), Chapter 5, Problem 1P , additional homework tip  3

After simulating the PSPICE circuit, the output voltage vo is shown in Figure 4.

Electric Circuits. (11th Edition), Chapter 5, Problem 1P , additional homework tip  4

From Figure 4, the output voltage vo=10V.

Conclusion:

Thus, the value of voltage vo in the given circuit is 10V.

A. The ECG signal of a person shows an irregular heartbeat of 180 beats per minute. You areasked to come up with a system that digitises this signal, using an analog-to-digitalconverter (ADC) with a reference voltage of 5 V. The digitised signal should have a resolutionof 1 mV or better.i) How many samples per second should your system take in order to fully capture the ECGsignal?ii)  What should the ADC’s resolution in bits be? Alternatively, how many quantisation levelsshould the ADC have; or how many bits per sample should the ADC have? B. You have successfully designed your ECG signal capture device. However, the person fromQuestion A is being examined in a room with fluorescent lights which have recently startedbuzzing. The digitised ECG signal appears to be very noisy, and the medical doctors arefinding it difficult to diagnose the patient. You suspect interference from the electrical mainsis to blame.You also notice that the ECG signal is very faint and not making full use of…
