Labels:text | diagram | font | line | number | black and white | plan | technical drawing OCR: Example EX2. CIR 1K 0.SUF This sample shows an active high pass filter. The op-amp has an input impedance of 10K , Vout an output impedance of 10 ohm, and a voltage Uin 50 UF gain of 10. 1K Use -1.33 for a freqency increment. The figure in the centre shows a simple model for the op-amp. Cearly, Vout is Rout#gm (V+-U-) 9M(V+-V-) Thus if the voltage gain is 10 and Rout is U- 10 ohm, gm must be 10.
