digital modulation
hi
i am looking for a tx/rx on a single chip that receives serial ascii or binary ( doesn't matter ) and modulates it with fsk or anything so that the rx receives it and decodes it back to serial ascii/binary.
is this IC what i amlooking for ?
hi
i have a project at college which is building a 8051 developement kit on a PCB. i have read about it but didn't understand a word.

hi
i would like to know the types of wafer smartcards and what is the diffrence between them.
also what is the deference between mounted smart cards and wafer ones ?
if i have i have some data to put on a gold wafer card, can i use a wafer funcard instead and still work on my satellite...
hi i just wanted to know what is the difference between hole mounted funcards and wafer funcards.
do the wafer type cards work on nokia receiver 9800 with viaccess 2 and irdeto 2 ?
does the programmer v1.2 in www.funcard.net support the wafer type ?
plz reply sooooooooooon
does the funcard programmer v1.2 in funcard.net
used to program the following types of cards :
Gold Wafer Card 16F84A + 24C16
Blue Wafer Card 16F84A + 24LC64
PicCard2 Wafer Card 16F628 + 24C64
Silver 2 Wafer Card 16F876/877 + 24LC64

about ur last idea about the hock up circuit using the counter
i worked on it but the was a problem
i took the input from the telephone line and put as an input to the 741 OPAMP as a comparator to convert the superimposed sine wave of the telephone line when ringing into square wave as a clock...
great idea
but i tried to decode the outputs of the dtmf decoder before picking up the phone and it didn't work.
i don't know why but it didn't
anyway thanx 4 ur response :)
thanx 4 ur response
the secret code is about 4 digits
this means that i will be able only to control 5 appliances and the digit zero is used to hookup the phone line
but may i ask u a question ?
after reading the documentation file and seeing the schematic of this teleremote control, from ur...
