An RC coupling circuit is an example of what type of filter?

Low pass filter

High pass filter

Band pass filter

All pass filter

Correct Answer : High pass filter

Explanation : An RC coupling circuit is an example of a high-pass filter because the AC component of the input voltage is developed across R and the DC voltage is blocked by the series capacitor. Furthermore, with higher frequencies in the AC component, more AC voltage is coupled.

Which instrument produces frequency domain information?

Oscilloscope

Beam analyzer

Frequency divider

Spectrum analyzer

Correct Answer : Option (D) : Spectrum analyzer

Explanation : The test instrument for producing a frequency-domain display is the spectrum analyzer. Like the oscilloscope, the spectrum analyzer uses a cathode-ray tube for display, but the horizontal sweep axis is calibrated in hertz and the vertical axis is calibrated in volts or power units or decibels.
