Given:

Amplifier has a gain of 15 and input waveform shown below.

Calculation:

For an amplifier, output voltage is product of gain and its input voltage.

  vo=Avin

  Wherevo=Output voltagevin=Input voltageA= Voltage amplifier gain

In the given figure, calculate the output voltage by the above formulae at different time to form a graph.

At t=0 ,output voltage will be

  vo = 15×(0 mV)=0 mv

At t=0.5 s ,output voltage will be

  vo=15×(50 mV)=750 mV

At t=1 s, output voltage will be

  vo = 15×(150 mV)=2250  mV

At t=1 .5s, output voltage

  vo=15×(50 mV)=750mV

At t=2s, output voltage

  vo=15×(0mV)=0mV

The output waveform for the given input is shown below.
