RE: uSDX

Detektor uruchomiłem. Cóż, jak stosuje się zamienniki to trzeba bardzo dokładnie porównywać ich dane techniczne z oryginałem, a to zrobiłem tylko pobieżnie. W przypadku układu SN74CBT3253 oba wyprowadzenia OE muszą być połączone z masą, natomiast w FST3253 wyprowadzenia OE działają niezależnie dla każdej z dwóch czwórek przełączników.
Z wyprowadzeń detektora wychodzi sygnał na poziomie (pik-pik) 40-50 mV przy podanym sygnale na wejściu SN74CBT3253 około 0,2 V (napięcie skuteczne). Co najważniejsze to, że słychać go w głośniku.
Nie analizowałem działania detektora i wzmacniacza, ale z pomiarów wychodzi mi na to, że w jednym kanale powinienem mieć sumę amplitud (po detekcji), a w drugim ich różnicę. Proszę o ewentualne uwagi w tej kwestii.
Eh, w chwili słabości pomyślałem sobie, że "złożę" jakieś mało-skomplikowane radyjko, a wyszło jak zwykle.
Pozdrawiam.
