luc Posted June 16, 2006 Share Posted June 16, 2006 caut asa ceva cu cablaj,cat mai simpla posibila,nu ma intereseaza sa variez frecventa ,ci doar amplitudinea la iesire Link to comment
BRANCA Posted June 16, 2006 Share Posted June 16, 2006 Depinde la ce il folosesti,adica ce stabilitate si coef distorsiuni vrei. O aplicatie simpla si ieftina in fisa tehnica LM 386.LM-ul costa cca 1 ron. La iesire poti pune divizoare pt reglare nivel semnal. Daca vrei si altceva cauta pe net 1 kHz sine wave generator sau similar. O aplicatie cu LM386,facuta dupa fisa tehnica,gasesti la http://octopus.freeyellow.com/sine.html Trebuia sa postezi la Diy!

luc Posted June 18, 2006 Author Share Posted June 18, 2006 nu are nimeni o schema?cu cablaj bineinteles,si cat mai simpla 2-3 tranzistori Link to comment
BRANCA Posted June 18, 2006 Share Posted June 18, 2006 Pt asa ceva nu ai nevoie de cablaj!Merge direct pe placa test,sau chiar pe o placa cu trasee trase cu cuterul! Pt tranzistori uita-te la: http://www.redcircuits.com/Page13.htm http://www.redcircuits.com/Page92.htm Link to comment
