Drive Circuits for Ultrasonics Transducer

Drive Circuits for Ultrasonics Transducer

(OP)
HI,

I'm currently working on the drive circuits for both transmitting and receiving circuits.

I'm trying to implement the phase-delay method to steer the scanning beams of 4 ultrasonics transmitters and there will be a receiver to pick up the signal reflected.

Most of the circuits that I found on the web are mostly drive circuits for a single ultrasonic transmitter.

I really have no idea on how to carry the phase-delay method to steer the scanning beams. Could anyone Please give me so directions or hints? Thank you so much!

By the way, the frequency is running at 40KHz.

suggestions are welcome.

Hi all,

beside using a 555 timer to drive or to send a ping in the transmitting circuit, is there any other ways? Please help!

I came accross with frequency modulation from the net, but I'm really have no idea with this method (freq Modulation). Could anyone pls help?

Cheers
