Answer True or False, then correct errors or explain if any:
1. The term pole in filter terminology refers to the feedback circuit.
2, A voltage shunt feedback with Ai-10, A-20, p 0.45, then Aif will be 1.
3. The integrator Op-Amp circuit can be used to produce square waves.
4. The equivalent circuit of the crystal oscillator is series and parallel (R, C) components.
5. The transistor in a class A power amplifier conducts for the entire input cycle.
6. Bypass capacitors in an amplifier determine the low and high-frequency responses.
7. The midrange voltage gain of an amplifier is 100. The input RC circuit has a lower critical
frequency of 1 kHz. The actual voltage gain at f- 100 Hz is 100.
8. The Bessel filter types produce almost ripple frequency response.
9. RC phase shift oscillators are based on both positive and negative feedback circuits.
10. In a high-pass filter, the roll-off region occurs above the critical frequency,
Q.1. Answer True or False and correct errors if found
1. In a certain Op-Amp. if Ad=3500, Ac=0.35, the CMRR=100dB.
2. The voltage series feedback can increase both input and output impedances.
3. A two-pole Sallen-Key high-pass filter contains one capacitor and two resistors.
4. The main feature of a crystal oscillator is the high frequency operation.
Each transistor in a class B power amplifier conducts for the entire input cycle.
✓ The Q-point must be centered on the load line for maximum class A output signal swing
7. The differentiator Op-Amp can convert the triangle waveform into sinewave.
✗Class AB power amplifier eliminates crossover distortion found in pure class A.
9. Wien-bridge oscillators are based on positive feedback circuits.
10. The band-reject filter is composed of multiplication of LPF and HPF.

- 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.

- A chemical processing plant requires a simplified safety control system to monitor critical conditions in one of its reactors. The system must evaluate three key parameters and activate two response levels. A combinational circuit with 3 sensors and 2 alarms needs to be designed for this purpose. Sensors: A: Reactor temperature (0 = normal, 1 = high) B: Reactor pressure (0 = normal, 1 = high) C: Mixture pH level (0 = normal, 1 = out of range) Alarms: X: Warning alarm Y: Activation of the emergency shutdown system System requirements: 1. The warning alarm (X) should activate when: At least two parameters are out of range. • Or when the temperature is high (A = 1) and any other parameter is out of range. 2. The emergency shutdown system (Y) must activate when: • All parameters are out of range simultaneously (A = 1, B = 1, C=1). • Or when the temperature and pressure are high simultaneously (A = 1 and B = 1), regardless of the pH level.
