Addition of two sinusoids, Electrical Engineering

Connect the 2 kHz (sin ωt) signal to input A of the "Adder" module

Connect input B to ground (GND).

Connect the outputof the"Adder"(GA+gB) to input A-CH1 of "Scope Selector".

Adjust the G control so that the output of the adder is ≈ 4Vpp sinewave. Use the PicoScope to verify this.

Disconnect the ground from the B input

Connect the (sin ωt) output of the "Audio Oscillator" module to the analogue input of the "Frequency Counter" module. Using the Δf control, adjust the audio oscillator (sin ωt) output to ≈5 kHz. Now apply this 5 kHz signal to input B of the "Adder" module. Ground input A of the "Adder".

Adjust the g control so that the output of the adder is a 4Vpp sinewave.
Note: do not adjust the G control.

Remove the ground from input A of the "Adder" module and reconnect the 2kHz message signal.

Observe and record the resultant waveform in both the time and frequency domain, noting all the important characteristics. (As per section 1 Single Sinusoid).
