- 1 For an OP-amp with negative feedback, the output is
- 2 Hysteresis is desirable in Schmitt-trigger since
- 3 The two input terminals of an OpAmp are labeled as
- 4 The amplifier used in digital to analog converter is
- 5 When a number of stages are connected in parallel, the overall gain is the product of the individual stage gains
For an OP-amp with negative feedback, the output is
For an OP-amp with negative feedback, the output is:
- Equal to the input
- Fed back to the inverting input
- Fed back to the noninverting input
- Increased
Correct answer: 2. Fed back to the inverting input
Hysteresis is desirable in Schmitt-trigger since
Hysteresis is desirable in Schmitt-trigger since
- Devices in the circuit should be allowed time for saturation and desaturation
- Effects of temperature would be compensated
- Energy is to be stored/discharged in parasitic capacitances
- It would prevent noise from causing false triggering
Correct answer: 1. Devices in the circuit should be allowed time for saturation and desaturation
The two input terminals of an OpAmp are labeled as
The two input terminals of an OpAmp are labeled as
- Differential and non differential terminals
- High and low terminals
- Inverting and non-inverting terminals
- Positive and negative terminals
Correct answer: 1. Inverting and non-inverting terminals
The amplifier used in digital to analog converter is
The amplifier used in digital to analog converter is:
- Difference amplifier
- Non inverter
- Summer
- Voltage follower
Correct answer: 3. Summer
When a number of stages are connected in parallel, the overall gain is the product of the individual stage gains
When a number of stages are connected in parallel, the overall gain is the product of the individual stage gains
- True
- False
Correct answer: 2. False
