Operational amplifiers provide cost effective means for signal amplification and filtering. 1.1 Objectives To understand simple operational amplifier circuits To gain further experience in using an oscilloscope, a function generator, and a digital multimeter (DMM) To explore saturation phenomenon To explore the frequency dependence of electronic component properties 1.2 Equipment: Tektronix TDS2002 digital oscilloscope; Agilent 33220A Function/Arbitrary Waveform Generator Hand-held DMM Triple Output DC Power Supply 1.3 Suggested reading: 7.17 1.4 Report format For this experiment you do not have to prepare a report. Use the REPORT BOOKLET to record and analyze results, and hand it in in lieu of a report. 2. Operational Amplifier Circuits Your task is to construct a simple op-amp circuit using a common (inexpensive) 741 operational amplifier. The circuit will be constructed on a breadboard (protoboard) using the 741 op-amp that is premounted in a DIP (dual in-line package). 2.1 Connection of the power supply. Each power supply contains two suppliers (denoted A supply and B supply respectively). To generate positive and negative voltages, the DC power supply must be connected in series. respectively)....
