I. Verification experiment 1. Experimental purpose ● Be familiar with calling the integrated operational amplifier from Multisim software. ● Call the signal generator and oscilloscope for simulation test. ● Master the connection and debugging of software and hardware circuits. 2. Experimental steps: (1) Be familiar with the circuit diagram structure (2) Turn off the power supply and connect the circuit according to the circuit schematic diagram, and check whether there are any wrong connection points, and then turn on the power supply. (Zero adjustment) (3) Input a sine signal and use a millivoltmeter to measure the input Ui and output Uo amplitude. (4) Input a square wave signal, use an oscilloscope to observe the output waveforms of Ui and Uo and draw its square wave and triangle wave voltage waveforms (voltage value, period). II. Design experiment 1. Experimental purpose Through the integral operation circuit design experiment, learn the design and debugging methods of simple integral circuits, understand the factors that cause integrator operation errors, and initially master the methods of reducing errors. 2. Design topic ① Design an integral operation circuit to convert a square wave into a triangle wave. It is known that the amplitude of the input square wave is 2V and the period is 1ms. III. Input and output waveforms
