[sdiy] multiplication thread

[Czech Martin]

sorry if I disturbed people with this long thread!
Thanx for all the responses.
So I got the following homework to do:

1.) dual OTA ringmod (13700)
2.) RC4200 ringmod
3.) single OTA ringmod
4.) 1495 ringmod
5.) discrete ringmod (finished)
6.) 1496 with predistortion ringmod
7.) real ringmod with transformers
8.) real ringmod with opamp balancing
9.) 633 ringmod (finished)


To be realistic, this won't be finished before summer vacations.
Perhaps a little earlier.
