I am using a Common Emitter amplifier to receive the reflected ultrasonic from an object.I also have to Integrate the transmitter and receiver to make an ultra-sonic proximity detector that can detect the presence of an object from a distance of 50 cm. And finally I have to Indicate the detection of the object by an audible tone.
I am using a 741 op amp and i need help with the design. any input will be highly appreciated.
