Unformatted text preview: ECE 209: Circuits and Electronics Laboratory Notes for Lab 3 (Operational Amplifiers and First-Order Circuits) 1. Comments on returned lab reports. In first lab report, all phase shifts should have been from quadrant III and not quadrant I. Lab reports should be formatted like reports (i.e., not lists ). Use kHz not KHz or KHZ. Small k is kilo; big K is Kelvin (temp. matters to circuits). For hand-drawn figures, use engineering graph paper , and write on the side with no grid lines. Photocopies will be clear of any distracting grid lines. 2. Operational amplifiers: see supplementary document for more information. Op. amps are useless when not in a feedback configuration. Extremely-high-gain negative feedback causes V- to track V +. Set V- node to V + signal; assume no current goes into the OA, and solve rest of circuit. 3. Linear systems: see supplementary document for more Laplace- and frequency-domain information. Each input signal instant is like scaled impulse that causes system output to ring like a bell. Convolution is the sum of all of the effects of each impulse. Before convolving, we must know the impulse response to find each of those effects....
