DESIGN OF ACTIVE FILTERS (LPF, HPF) Aim: To design and test the low pass filter and high pass filter using op-amp Apparatus: 1) Op-Amp (µA )- 2 No’s 2) DC Power Supply (12 12) V 3) CRO (MHz range). LABORATORY PROCEDURE: Exercise 1 Low Pass Filter 1. Using the UA dual opamp, construct on your breadboard a low pass filter using the resistor and capacitor values calculated and simulated in the prelab. You may have to adjust component values based on the values that are available in real resistors and www.doorway.ru Size: KB.

Fundamentals of Low-Pass Filters Active Filter Design Techniques Tschebyscheff Low-Pass Filters The Tschebyscheff low-pass filters provide an even higher gain rolloff above f C. However, as Figure 6 shows, the passband gain is not monotone, but contains ripples of constant magnitude instead. Active Butterworth Low-Pass Filters Systems and Signals Laboratory © Prof. Mohamad Hassoun Contents: Pre-lab Lab activities: Design and build an active circuit that realizes a fourth-order low-pass Butterworth filter and experimentally determine the frequency response (magnitude and phase), step-response and impulse-response. Figure 1 shows simple low pass filter along with the ideal and actual filter magnitude responses. The low pass filter is constructed from only two passive components: a resistor and a capacitor. All of the power for the circuit is supplied by the input signal. Thus the filter shown in Figure 1 is a low pass, passive filter. An active filter.

This first-order low pass active filter, consists simply of a passive RC filter stage providing a low frequency path to the input of a non-inverting operational amplifier. The amplifier is configured as a voltage-follower (Buffer) giving it a DC gain of one, Av = +1 or unity gain as opposed to the previous passive RC filter which has a DC gain of less than unity. If an active filter permits only low-frequency components and denies all other high-frequency components, then it is termed as an Active Low Pass Filter. Active low pass filters are made up of Op-Amp. The input to the Op-Amp is high impedance signals, which produces a low impedance signal as output. The performance of the amplifier plays a very important factor when designing an active low pass filter. Lab Frequency response of an active low-pass active 1.
