A complete course in designing active and passive filters

The Analog Filters interactive CD-ROM course provides everything from a refresher on the basic knowledge required to design filters to a course in advanced filter design.

Interactive virtual laboratories, animations, and diagrams allow you to actually see on screen how filters work and thus help you to more easily understand the material presented. A SPICE circuit simulation engine allows you to experiment with and simulate all filter designs.

Analog Filters Key Features

• Explanation of filter design theory
• Interactive laboratories to assist conceptual understanding
• Expert systems for active and passive filter design
• SPICE simulation of all filter circuits
• E12 normalisation capability

Analog Filters is broken into five main sections:

Revision provides underpinning knowledge required for those who need to design filters. Topics covered include:

• Signal representation: Amplitude, Frequency, Logarithm scale, Decibels, natural decay, phase, relative phase.
• Components: Resistance, Resistor properties, resistor phase, capacitance, capacitor properties, capacitor phase, inductance, inductor properties, inductor phase
• Tuned circuits: Parallel , serial
• A low pass filter: Potential divider, simple low pass filter, frequency response, bode plot, tuning the filter
• Active filters: Op amps, voltage follower, non-inverting amplifier, inverting amplifier, first order active filter
• Harmonics and distortion: Harmonics, harmonics on an analyzer, making a square wave

Filter Basics is a course in terminology and filter characterization, important classes of filter fundamental mathematics, filter order impedance and impedance matching, and effects of different filter types. Topics include:

• Terminology: Low pass, high pass, band pass, band stop
• Filter types: Bessel, Butterworth, Chebyshev, Elliptic (Cauer), inverse Chebyshev
• Filter order: First, second, third, fourth
• Impedance: Passive filters, active filters
• Matching: Passive L, Passive T, Passive Pi
• Filter effects: Pass-band ripple, group delay, mismatched impedance
• Filter design: State variable filter, dual amplifier filter

Advanced Theory topics covered include:

• Using filter tables: Define pass band shape, define pass band ripple, define frequency band, select filter order, normalized tables, de-normalizing for frequency, de-normalizing for impedance, high pass filters, band pass filters, band stop filters, active filters
• Mathematics: Half power point, transfer function, S plane, first order transfer function, second order transfer function, poles and zeroes
• Active Filters: How to ..., first order low pass, first order high pass, second order low pass, second order high pass, band pass

The two Filter Design sections include introduction and expert level materials. The virtual laboratories guide users through basic requirements of capture and filter synthesis to simulation and E12 normalization for a range of both passive and active filters. Filter Design includes a suite of filter synthesis and simulation tools.

Please note that the included simulation and synthesis tools do not allow you to save your work to disk, they are only intended as learning aid tools to understand filter design and to see the effects of changing parameters on screen.
