Unformatted text preview: Lab 10 C.J. Gorrell Operational Amplifiers ENME350 0102 Lab Partners: 3/27/10 Pic tu re 4 I. Objective To understand how an amplifier acts in a circuits, and to understand the relationship between frequency and gain. II. Instruments Used A. Power Supply B. Function Generator C. Digital Multimeter D. Oscilloscope III. Parts Needed A. Breadboard B. 1Kohm, 10kohm resistors C. 741- operational amplifiers IV. Voltage Variation on an Inverting Amplifier A. Experimental Setup: Using the circuit below, analyze the output voltage of the amplifier, as the voltage of the function generator is increased. B. Data: CH1 (Vin) Ch 2 (Vout) volts Phase degrees 320mV 1.76 180 400mV 2.96 180 480mV 3.84 180 560mV 4.16 180 640mV 5.48 180 880mV 6.88 180 980mV 7.28 180 1.04V 7.52 180 1.2V 7.52 180 1.4V 7.52 180 1.6V 7.52 180 1.8V 7.52 180 2V 7.52 180 2.2V 7.52 180 C. Calculations: Vout=-(R2/R1)*Vin D. Analysis- From the data it can be seen that the inverting amplifier produces an output from the input that is proportional to the input voltage. The period of the output and input the input that is proportional to the input voltage....
