FILTER CIRCUITS Introduction Circuits with a response that depends upon the frequency of the input voltage are known as filters. $~�1012������O�0 �E� In circuit theory, a filter is an electrical network that alters the amplitude and/or phase characteristics of a signal with re- spect to frequency. 2Active Filters: Theory and Design transfer function magnitude versus frequency is called the amplitude responseor sometimes, especially in audio applications, the frequency response. The design process of the filters can consist of different types of architectures, where the two most common are named Sallen and Key, and Multiple Feedback (MFB) architecture In this assignment the filter is an active low-pass filter with a Butterworth response. %%EOF They are low-pass, high-pass, band-pass, and band-stop. ���;L�u�j�h�+��([��Zd�����ⴍ+���2�&C��1� Unlike a passive high pass filter which has in theory an infinite high frequency response, the maximum frequency response of an active filter is limited to the Gain/Bandwidth product (or open loop gain) of the operational amplifier being used.

Types of Active Filters. ��d �����. In order to move the filter frequency to the desired frequency a denormalization must be performed. As the frequency is changed, the value of the reactive impedance changes, and the voltage divider ratio changes. As the name suggests, active filters use ‘active’elements as a part of their circuit These may consist of either opamp, BJT or any FET Generally, opamps are used in designing active filters Why opamps !! Filter circuits are used in a wide variety of applications.

The nonlinear loads generate harmonic current which distorts the voltage waveform at PCC. To achieve the correct shaping, one considers the Fourier transform of the filter, and designs it so that the magnitude of this transform has the desired shape. For active filters, the impedance denormalization is a free parameter that can be used to adjust the final values of the components.
