[PEDA] Simulate a sweep oscillator in Protel 99SE

[Brian Guralnick]

If protel can accept a streaming data file with the sine wave in it, you can 
generate the sine sweep in any simple programming language, IE Basic, or, it 
might be possible to use MS Excel to create a data table which can be 
exported as ASCII text.



I once had to create such a sweep back in 1992 when I designed my first TV 
test pattern generator.  Unfortunately, it was written in Amiga Basic & has 
disappeared long, long ago.
