Hi all, I'm new to this.
I have a Spartan 3AN FPGA board and I'm wanting to make an extension board that does measurements of ultrasonic frequencies at 40kHz.
The range that would be desired is 5 metres.
I haven't used the ADC/DAC yet so I would like to use these for connecting the TX/RX transducers. I am wondering how to make a circuit that will interact with the ADC/DAC?
I know I will need to amplify the signal that is received but when transmitting would I need to amplify before I send as well?
If anyone could help, greatly appreciated.
