Its not quite as simple as that. In order to make it work with the TI
protocol, you need atleast one transmitter, one reciever, and a
microprocessor with high speed ADC and DACs.
To make the design easier, you could use two transmitters, two recievers,
and a microcontroller with average sound ADC and DACS.
Remember, even for the one transmitter/reciever for each calc, you need
atleast two frequencies that aren't near each other. For the 2
transmitter/receiver setup you'd need 4.
