Welcome to PC-ECAP


 PC-ECAP is an easy to use AC circuit analysis program which analyzes circuits
 consisting of resistors, capacitors, inductors, transformers, transistors
 (both bipolar and FET's), operational amplifiers and transconductance
 amplifiers.

evaluation period, you must register your copy with Circuit Systems.

To register PC-ECAP, just fill out the form contained in the ORDERFRM file
and mail it to the address indicated on the form.  Upon receipt of your 
registration, Circuit Systems will send you a REGISTERED version of PC-ECAP.  
The registered version will not contain the input requests found in the 
evaluation copy. 

Registration also entitles you to technical support and low-cost updates.
