PPT-Coupling and Filter Circuits

Chapter 26 Filter a device that removes or filters or attenuates unwanted signals and keeps and sometimes magnifies the desired frequencies Attenuation opposite of gain and magnification To shrink or remove. Filters, frequency response, time domain connection, bode plots, resonant circuits.. Outline and topics. Low-pass filters. High-pass filters. Other filters. Resonance (Ch 20). Ideal op-amps and active filters. Loading tends to make filter’s response very droopy, which is quite undesirable. To prevent such loading, filter sections may be isolated using high-input-impedance buffers. ‘A’ is closed-loop gain of op amp. EE221. Unit 7. Instructor: Kevin D. Donohue. Active Filters, Connections of Filters, and Midterm Project. Useful Circuits:. . Describe the transfer functions of these circuits:. Non-Inverting Op Amp: gain = (1 + . Most typical applications require op amp and its components to act linearly. I-V characteristics of passive devices such as resistors, capacitors should be described by linear equation (Ohm’s Law).
