I need two existing circuits to be altered to accommodate different (given) transducers (and hence different frequencies).
You are free to either completely redesign the circuits or simply change the values of the components of the existing circuits to accommodate the new transducers.
The circuits and the current approach are described here: [url removed, login to view]
Circuit 1 drives a given ultrasound transmitter via an arduino uno board.
Circuit 2 amplifies the signal of a given ultrasound receiver so it can be read by another arduino board.
The datasheet of the new transducers can be found here:

please note that transmitter and receiver are two different units.
