Question

A circuit is a non-inverting comparator, How would the output change, if we replace the Zener diode with a new one with a breakdown voltage of 3V?

a) The output voltage will have a lower duty cycle.
b) The output voltage will be zero.
c) The output voltage will have a higher duty cycle.
d) The duty cycle of the output voltage will be 50%.

Answer 1

What is the advantage of using comparators with hysteresis?

a) Setting the voltage gain
b) Decrease the power dissipation
c) Eliminating the effect of noise
d) Limiting the output amplitude

Answer 2

Inverting Schmitt Trigger, the supply voltage is ± 12V. Suppose VIN = +3 V, the output voltage will be:
R1 = 10kΩ
R2 = 10kΩ

a) +7v
b) -10v
c) +5v
d) +10v

Answer 3

c) The output voltage will have a higher duty cycle.

Answer 4

c) Eliminating the effect of noise

Answer 5

To determine the output voltage of the inverting Schmitt Trigger, we need to consider the voltage divider created by resistors R1 and R2.

The output voltage is given by the equation:

Vout = -Vin * (R2 / R1)

Given that Vin = +3V, R1 = 10kΩ, and R2 = 10kΩ, we can substitute these values into the equation to calculate the output voltage:

Vout = -3V * (10kΩ / 10kΩ)
Vout = -3V * 1
Vout = -3V

Therefore, the output voltage will be -3V.

So, the correct answer is:
b) -3v
