SOME NOTABLE QUOTES ABOUT PCFILT:
ANDREW LAUNDRIE
"In spite of its analysis and synthesis power, the software is relatively easy to operate, requiring only a knowledge of filter types and responses. The software includes network analysis and optimization for full analysis and fine-tuning of a design."
"PCFILT offers powerful optimization routines not often found in low-cost software tools. Return loss, group delay, or amplitude flatness can be optimized with seven store-and-recall network analysis setups. A tune mode also allows operators to experiment with different component values at any branch in a filter design."
"Filter designers have a variety of computer-aided-engineering (CAE) software tools at their disposal, mostly for IBM personal computers and compatible machines. The range of tools includes simple, low-cost packages and high-cost engines with elaborate graphical user interfaces (GUIs). While PCFILT from ALK Engineering may not be among the most impressive filter design tools in terms of graphics, it does what a filter CAE package should do: design a wide range of filters, from audio frequencies to microwave, quickly and accurately."
"When operating on an 80486 personal computer, the software ran flawlessly. The software opens to a main control menu from which an operator can start a new design or recall a previous circuit file. When choosing to start a new design, the software switches to a second menu with a choice of filter types, including bandpass, lowpass, highpass, notch, equalizer, and resistor pad types. Upon selecting one of these filter types, the software proceeds to a third menu based on the filter."
"For the purpose of evaluating the software, a simple bandpass filter was designed, with a center frequency of 915 MHz, as might be used in RF- identification (RFID) applications."
"PCFILT is supplied with a simply-printed yet comprehensive operators manual (with dedication to Klappenberger's late friend Fredrick J. Radler, who had been involved in some of the transmission line designs). A thorough reading of this manual should help avoid any problems or surprises when operating the software. Nonetheless, in designing the 915-MHz bandpass filter, the software was used directly out of the box with no difficulties. For operators with access to Touchstone linear simulation software from HP-EEsof (Westlake Village, CA), PCFILT can convert its own filter files to Touchstone compatible files for full linear simulation."
"PCFILT is the filter design and analysis program for every level of designer sophistication. It has simple, easy to understand and learn command input and extreme flexibility in schematic entry and editing, entering complex multi-element branches in quick, logical manner. It gives accurate graphs that are readable and understandable, automatic or manual point-by-point sweep. It was produced by an experienced ex-technician who knows what steps it takes from the PRACTICAL side of the business, and he has built them all into the program."
"It may not have all the ultimate capabilities with regard to sophistication in synthesis, but it more than makes up for it in flexibility of producing practical designs."

"PCFILT is an extremely handy filter designers's tool. Particularly impressive is the seamless way a designer can move from the design application into the analysis application. The analysis portion provides both tabular as well as graphic output and the user can change plotted performance from transmission, return loss, group delay and phase linearity responses at the touch of a keystroke or he can compare all of these responses simultaneously. For lumped element design, there are multiple options for transforming from the internal impedance of the filter designed to any desired line impedance. PCFILT also has an extremely useful editing capability, making it an extremely flexible design tool."
