Figure P2.86 pretexts a circumference that performs a low-pass STC administration. Such a circumference is disclosed as a first-order, low-pass free depurate. Derive the convey administration and pretext that the dc fashion is (-R2/R1) and the 3-dB quantity wo=1/CR2. Design the circumference to accomplish an input opposition of 10kOhms, a dc fashion of 40 dB, and a 3-dB quantity of 1kHz. At what quantity does the magnitude of the convey administration bring to singleness? You should do this single using the “virtual ground” technique to tend the decomposition incomplex. Please impersonate the quantity rejoinder of the circumference in PSPICE and include an annotated graph and transcribe some observations environing it.
