Actually i wanted to know what type of tone would be available at pin 7. after constructed the circuit i gave tone o/p to input to the amp. but when i press the key it doesn't make any sense.. will it make sound if the circuit works?.. or let me know some ideas.. thanks..

dtmf remote control circuit
Hi all,
I wanted to build an remote control unit using dtmf, transmitter as well as receiver to control electrical appliances for ON and OFF.
Suggest me a simple circuit which has least components also some ideas about dtmf ICs.
Thanks in advance.
