본문내용
Set the generator to provide a 1 Vp-p sine wave at 500 Hz.
Using 10x probes, display node A on channel 1 and node B on the channel 2.
Analysis: Show the input/output signal and calculate the close-loop gain, phase-difference.
Above circuit is what I drawn using the Pspice program
Above picture was obtained by the experiment. The first signal is input signal and the second signal is output signal. The set input signal was 1Vp-p sine wave at 500Hz. Each cell’s horizontal length means 500μs and sine wave has the period which is same with 4 cells wide. Therefore, T = 500μs X 4 = achine showed the incorrect result. As the teaching assistance said, it would be right if I translate the 1Vp-p value as just 1V peak value.
The circuit is inverting op amp. So, the close-loop gain of inverting circuit is G = - (R2 / R1). Substituting the constants, G = - (10k / 10k) = -1. The minus sign in the result means the 180° phase shift of the input signal.
