Aeronautical & Aerospace Engineering : Avionics - Quiz(MCQ)

Differential filters

Continuous filters

Active filters

Passive filters

Correct Answer : Passive filters

Explanation : Simple filters created by using resistors and capacitors or inductors and capacitors are called passive filters because they use passive components that do not amplify. In communication work, many filters are of the passive LC variety, although many other types are used.

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.
