Decoder Ic. Prototype of mt8870 ic based dtmf decoder circuit. Give common 5 v supply to both circuits.
Decoding is essential in applications like data multiplexing memory address decoding and 7 segment display. Now press keys 1 to 9 on dtmf tone generator circuit. A decoder is a multiple input multiple output logic circuit that changes codes i ps into coded o ps where both the inputs and outputs are dissimilar for instance n to 2n and binary coded decimal decoders.
The design is also made for the chip to be used in high performance memory decoding or data routing.
Now press keys 1 to 9 on dtmf tone generator circuit. A decoder is a combinational circuit which has many inputs and many outputs. It is used to convert binary data to other codes. Mostly remote control applications have this technology.
