#186378 - ultrasonic receiver problem |
Hi all
I am using ultrasonic TX and Rx of 40KHZ.I have no oscilloscope to check the response of TX & RX.when powered up, beep sound was coming from transmitter(so i am thinking that TX is working). In the receiver section i am using audio amplifier circuit with Lm386 as well as general op amps.without connection of the receiver output to the circuit also,i am getting the signal on the output.How can i check the response of the receiver circuit using multimeter. how would i know that the both transmitter & receivers are working or not.please give me a guidance regarding this. If you have any circuit please post it. Thanks in Advance |
