PC-ECAP v3.01 - AC circuit analysis.
Calculates magnitude, phase, group delay,
impedance, VSWR, and return loss. Now also
calculates TRANSIENT response with one of 8
waveforms as input. Handles circuits with up
to 90 nodes and 1000 components. Completely
menu driven, very easy to use. Many features.
High res plots on screen or 9/24 pin printer
or HP LaserJet/DeskJet. All video adapters
supported. Shareware $89.
Welcome to PC-ECAP v3.01
PC-ECAP is an easy to use AC circuit analysis program which analyzes circuits
consisting of resistors, capacitors, inductors, transformers, transmission
lines, transistors (both bipolar and FET's), operational amplifiers and
