Two engineering design software items some may want to check out:

1. My latest issue of Electronic Products (Engineering Mag) has a full page
ad from Linear Technology in it. They are offering free download or free CD
ROM filter design software. Really cool !!

Free FilterCAD 3.0 Software

-Design active RC or switched-C filters up to 16th order. -Supports both
active RC and switched capacitor filter
  IC's, Designs all types: lowpass,highpass,bandpass,
  notch.
-Provides a variety of responses, Butterworth,Bessel,
 Chebychev, Elliptic and custom responses.
-Provides circuit diagram, frequency response, phase
  response, group delay, step response, pulse response,
  and sine burst response. Also prints results.....

2. Another free cool site for design is now provided by National
Semiconductor. It was a $10 per use simulation tool group that is web based
formerly called WebSIM. It is now free to use and named Webench 2.0. You
can check it out at: http://www.webench.national.com

Later... enjoy !
