The text starts with the fundamentals of network synthesis and discusses about the network functions in details followed by synthesis of one-port networks and transfer functions. Then the text gives a glimpse into the important filters used in network design. The performance of any network depends on how well it can perform its functions and its robustness despite distortions. Parameters like sensitivity and gain are then dealt with in detail. The book is intended for those readers who are well-versed with the basic concepts of electrical network and filters.

The term Cauer filter can be used interchangeably with elliptical filter, but the general case of elliptical filters can have unequal ripples in the passband and stopband. An elliptical filter in the limit of zero ripple in the passband is identical to a Chebyshev Type 2 filter. An elliptical filter in the limit of zero ripple in the stopband is identical to a Chebyshev Type 1 filter.

An elliptical filter in the limit of zero ripple in both passbands is identical to a Butterworth filter. The filter is named after Wilhelm Cauer and the transfer function is based on elliptic rational functions. This gives the filter a linear phase response and results in it passing waveforms with minimal distortion.

The Bessel filter has minimal distortion in the time domain due to the phase response with frequency as opposed to the Butterworth filter which has minimal distortion in the frequency domain due to the attenuation response with frequency. The Bessel filter is named after Friedrich Bessel and the transfer function is based on Bessel polynomials. Treating it as a one-port network, the expression is expanded using continued fraction or partial fraction expansions. The resulting expansion is transformed into a network usually a ladder network of electrical elements.

Taking an output from the end of this network, so realised, will transform it into a two-port network filter with the desired transfer function. Wilhelm Cauer following on from R. Foster [10] did much of the early work on what mathematical functions could be realised and in which filter topologies.

The ubiquitous ladder topology of filter design is named after Cauer. The most well known ones are; [12] Cauer's first form of driving point impedance consists of a ladder of shunt capacitors and series inductors and is most useful for low-pass filters.

Cauer's second form of driving point impedance consists of a ladder of series capacitors and shunt inductors and is most useful for high-pass filters. Foster's first form of driving point impedance consists of parallel connected LC resonators series LC circuits and is most useful for band-pass filters. Foster's second form of driving point impedance consists of series connected LC anti-resonators parallel LC circuits and is most useful for band-stop filters.

The general form of network functions is given below: Now Taxable payments annual report lodgment the help of the above general network function, we can describe the necessary conditions for the. Cauer's second form of driving point impedance consists of a ladder of network capacitors and synthesis inductors and.

Main article: Butterworth filter Butterworth filters are described as maximally flat, meaning that the response in the frequency domain is the smoothest possible curve of any class of filter of the equivalent order.

The full design calculations from the relevant mathematical functions and polynomials are carried out only once. From the above discussion we conclude one very simple result, If all the coefficients of the quadratic polynomial are real and positive then that quadratic polynomial is always a Hurwitz polynomial.

An elliptical filter in the limit of zero ripple in the stopband is identical to a Chebyshev Type 1 filter. A different prototype is required for each order of filter in each class. In the frequency domain, network functions are defined as the quotient obtained by dividing the phasor corresponding to the circuit output by the phasor corresponding to the circuit input. Cauer's second form of driving point impedance consists of a ladder of series capacitors and shunt inductors and is most useful for high-pass filters.

The order of the filter is the number of filter elements present in the filter's ladder implementation. The Bessel filter is named after Friedrich Bessel and the transfer function is based on Bessel polynomials. There are three mains necessary conditions for the stability of these network functions and they are written below: The degree of the numerator of F s should not exceed the degree of denominator by more than unity.

Generally speaking, the higher the order of the filter, the steeper the cut-off transition between passband and stopband. Main article: Prototype filter Prototype filters are used to make the process of filter design less labour-intensive. The Cauer filter has a faster transition from the passband to the stopband than any other class of network synthesis filter. The Bessel filter is named after Friedrich Bessel and the transfer function is based on Bessel polynomials. Main article: Butterworth filter Butterworth filters are described as maximally flat, meaning that the response in the frequency domain is the smoothest possible curve of any class of filter of the equivalent order.

Filters, the essence of any network design, have been appropriately handled in the book. In simple words, network functions are the ratio of output phasor to the input phasor when phasors exist in the frequency domain. A different prototype is required for each order of filter in each class. About Electrical4U Electrical4U is dedicated to the teaching and sharing of all things related to electrical and electronics engineering. The performance of any network depends on how well it can perform its functions and its robustness despite distortions. This is also sometimes called a type I Chebyshev, the type 2 being a filter with no ripple in the passband but ripples in the stopband.
