ECET220 Lab 6 –Filters and Oscillators 2020 solution docx DeVry University Part A-Active Filters Week six addresses the concept of active filters and oscillators. The low, high, bandpass and ... notch active filters, their circuits, and operating parameters are covered. The Wein-bridge RC oscillator, its configuration, operation and circuit is discussed. A. Identify the gain-versus-frequency response of basic filters. a. Draw the frequency response of a low-pass, high-pass, bandpass, and a notch filter. Label each axis, the critical frequency, bandwidth and the 3-dB point. Low High b. What is the “order” of a filter? How is an order created? B. Simulate the frequency response of an active low-pass filter such as a Butterworth filter. a. Given the following circuit, calculate the critical frequency and the closed-loop gain. = = [Show More]
