-Use the first waveform generator as the carrier signal providing a 4V amplitude, 2.5V offset, 1 kHz triangle wave excitation to the circuit. Use the second waveform generator as the modulation signal with 3V amplitude, 2.5V offset, 50Hz sine wave.+Use the first waveform generator as the carrier signal providing a 4V amplitude ​peak-to-peak, 2.5V offset, 1 kHz triangle wave excitation to the circuit. Use the second waveform generator as the modulation signal with 3V amplitude ​peak-to-peak, 2.5V offset, 50Hz sine wave.
  
 Supply the op amp with +5V from the power supply. Configure the scope so that the input signal is displayed on channel 1 and the output signal is displayed on channel 2 . Supply the op amp with +5V from the power supply. Configure the scope so that the input signal is displayed on channel 1 and the output signal is displayed on channel 2 .
