Sziasztok!

�n egy �ve csin�lgatom m�r ...
A vil�gos, s�t�t cs�kokat DC, ill. AGC probl�m�k okozz�k.

Ha a kapcsol�sban van a jel �tj�ban elk�, az DC hib�t okoz.
Emiatt az eg�sz �ramk�rt �jra kell tervezni, �n k�t m�veleti er�s�t�t (AD810) haszn�ltam a jel �tj�ban. Az egyik a norm�l, a m�sik az invert�lt vide�jel dolgait int�zi. A norm�l, olcs� anal�g kapcsol�kat felejts�tek el, nagyon sokat romlik a jel, ha kereszt�l megy rajtuk.

Az AGC probl�m�t a m�r le�rt ok okozza, de egyszer�en megoldhat�, RF szinten kell leosztani a jelet a k�v�nt id�ben, �gy a tuner, ill. a KF m�r j� jelet kap, nem fog �ssze-vissza szab�lyozni. Egy j� �tlet nyerhet� a MaxiNew2 kapcsol�s�b�l, b�r az �rt�kek nem korrektek.

A General Instrument/Jerrold dek�dereknek k�dolatlanul �tk�ldik az inf�t, hogy milyen �zemm�dban m�k�djenek. Mindezt k�zel 20 �ve, k�zel v�ltozatlan form�ban teszik, amat�r�k ... Ezt n�lunk a 6., ill. a 318. sorban t�rt�nik.

Szerintem, hogy seg�ts�k egym�st, kellene egy web oldalt k�sz�teni, ahov� a gazd�n kereszt�l mindenki felrakhatja azt, amit fejlesztgetett, amit kim�rt ...
Esetleg a Yahoo Groups is j� lehet.

�dv
