Objective To identify common filter circuits and corresponding transfer functions

Passive Filter Configurations Passive filters are composed of resistors, capacitors, and inductors Limited by ability to amplify a filtered signal Low-pass: passes low frequencies High-pass: passes high frequencies

Passive Filter Configurations Bandpass: passes low frequencies up to a cut-off frequency and passes high frequencies beyond a second cut-off frequency, but does not pass frequencies in between

Unformatted text preview: Output magnitude and cut-off frequencies are not altered with addition of a resistive load, as in passive filters Usually do not employ inductors, since inductors are expensive and difficult to acquire exact inductance in practice Low-pass: passes low frequencies High-pass: passes high frequencies Active Filter Configurations A cascading low-pass and high-pass active filters yields a bandpass filter (see example) Note: filters can be cascaded, and the result is the product of their transfer functions Examples See document: dis_filter_examples...
