Question

If signal is passed through integrator it ___ amplitude of noise signal

Answer 1

If signal is passed through integrator it reduces amplitude of noise signal.

Answer 2

If a signal is passed through an integrator, it reduces the amplitude of the noise signal.

• An integrator is used in the conversion of square waveforms to triangular waves and hence, they perform the role of filters.
• In the case of an input sine wave, the integrator acts as a simple low pass filter that reduces the output waveform.
• A triangular input wave will get transformed to a since when passed through an integrator.
• Thus, when an input wave is complex, the integrator will remove the higher frequencies from it leaving behind lower frequencies.
• This means the amplitude of the signals gets reduced when passed through an integrator.
