Hi Chris,

Thanks for your reply and info. The work you did is very good and makes understanding a square wave very easy. I know there is a way to take a raw set of data and perform a Fourier analysis but I am sure it involves equipment I don’t have and is most likely to expensive to buy for one person. I did get a digital multimeter 22-881 from Radio Shack the will permit me to measure freq., electric fields and a host of other things. It was well worth the 50 bucks.

I am in contact with the people that I purchased the unit from in N.Z., unfortunately they are just selling the system and have gone back to the manufacture with my request. This will take time.

The system I have has many functions, one of which is a brain tuner BT9. I was able to analyze it through Cool Edit and found many freq. ranging from 100 hz to over 20 khz. In intervals of about 100 hz. This is interesting as the unit is only suppose to generate 10.2 khz. As I later found out from other sources the freq. is not the important factor with BT systems the pulse is. These systems through out over 500 freq. in an electrical pulse at 111 cycles per second or 111 hz. Through the use of CE I was able to calculate the pulse rate. Things sure would be a lot easier with a manual but that is one of the short comings of this deal. The unit works well, has a lot of functions and is priced right but there is very little info. I am new to Rife so the black board is blank and needs to be full.

Many moons ago I use to teach DE but I am so rusty it some times hurts. Thanks for all your help.
