Gain and Frequency Response Quiz

What does an amplifier do?

• Changes the frequency of a signal

• Decreases the amplitude of a signal

• Increases the amplitude of a signal

• Has no effect on the signal

How does an amplifier change the strength of a signal?

• By distorting the waveform of the signal

• By decreasing the frequency of the signal

• By reducing the amplitude of the signal

• By increasing the amplitude of the signal

What is the cut-off frequency of a filter?

• The frequency at which the filter's output power is higher than its input power

• The frequency at which the filter stops working

• The frequency at which the filter's output power is lower than its input power

• The frequency at which the filter's output power is half of its input power

How does the cut-off frequency affect the filter's performance?

• It has no effect on the filter's performance

• It changes the color of the filter

• It determines the filter's temperature

• It determines the frequency at which the filter starts to attenuate the input signal.

What is bandwidth in the context of frequency response?

• Range of frequencies over which a device or system can operate effectively

• The number of frequencies a device can handle

• The speed at which frequencies are processed

• The amplitude of frequencies in a system

How is bandwidth related to the range of frequencies a system can handle?

• Bandwidth is unrelated to the range of frequencies a system can handle

• Bandwidth is directly related to the range of frequencies a system can handle.

• Bandwidth is inversely related to the range of frequencies a system can handle

• Bandwidth is only related to the amplitude of frequencies a system can handle

What is resonance in the context of frequency response?

• The frequency at which the system's output is zero

• The frequency at which the amplitude of the system's output is maximized

• The frequency at which the amplitude of the system's output is minimized

• The frequency at which the system's output is constant

Name two types of filters used in frequency response.

• fast-pass filter and slow-pass filter

• up-pass filter and down-pass filter

• left-pass filter and right-pass filter

• low-pass filter and high-pass filter
