In January, 2010, Iowegian International Corporation released Version 5.0 of ScopeFIR™, the DSP professional's FIR filter design tool of choice. (See What's New in ScopeFIR 5 for more information.)

Registered users of all previous versions of ScopeFIR are eligible to upgrade to Version 5 for just $149, which is a savings of $150 compared to the $299 cost of a new ScopeFIR 5 Professional registration.  To upgrade:

1. Download and install ScopeFIR 5. The installer will not overwrite your ScopeFIR 4.x installation so you should install it to a different directory than ScopeFIR 4.x.
2. Purchase your upgrade registration.
3. You will receive your upgrade registration via e-mail. Enter the key to enable the Professional Edition of ScopeFIR 5.
