Linear Wave shaping

The circuit shown is

• an integrator

• a low-pass filter

• both of the above

• none of the above

The circuit for a high-pass filter is the same as the circuit for

• an integrator

• a differentiator

• both of the above

• none of the above

Across which component the output of a low-pass filter is taken?

• Resistor

• Capacitor

• Inductor

• All of the above

What is the main purpose of a low-pass filter?

• To allow high frequencies to pass

• To block low frequencies

• To allow low frequencies to pass

• To amplify all frequencies

In a differentiator circuit, the output is proportional to:

• The integral of the input

• The derivative of the input

• The average of the input

• The square of the input

What is the effect of increasing the capacitance in a low-pass filter?

• Increases the cutoff frequency

• Decreases the cutoff frequency

• No effect on the cutoff frequency

• Increases the gain

Which type of filter would you use to eliminate high-frequency noise from a signal?

• High-pass filter

• Low-pass filter

• Band-pass filter

• Band-stop filter

In a high-pass filter, what happens to the output as the frequency of the input signal decreases?

• The output increases

• The output decreases

• The output remains constant

• The output becomes zero

What is the primary characteristic of a band-pass filter?

• Allows all frequencies to pass

• Blocks all frequencies

• Allows a specific range of frequencies to pass

• Only amplifies low frequencies

In a low-pass filter, what happens to the output as the frequency of the input signal increases?

• The output increases

• The output decreases

• The output remains constant

• The output becomes zero
