25%

50%

100%

200%

Correct Answer : 50%

Explanation : Duty cycle is the ratio of the duration of the positive alteration t1 to the period T expressed as percentage. D= t1⁄T*100 = t1⁄2t1 * 100 = 50%.

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.
