Ja, en processor. Husk at holde digitale og analoge  






Jeg bruger digitale potentiometre til at trimme offset og lignende. Til  
variabelt gain, bruger jeg analoge multipleksere, der styres digitalt,  

og forsyningsveje. Hold anal oge og digitale signaler adskilt. Det er  
ikke let, men dog muligt.

Hej Uffe

Nu er signalbehandlingen meget speciel i vore systemer, da de er baseret  

musik muligvis ikke (omend en del synes meget rytmisk og synkront ...)




Jeg bruger digitale potentiometre til offset justering i den analoge  

signalvejen, og her er der heller ikke problemer. Men igen: Man skal  


meget kritisk.
