yes, all I care about is the signal in the middle that looks like triangle. The first peak is always there, the signal is the middle is the reflection signal that I want. I calculated the time constant based on:
capacitor-resistor combination will establish the time constant ��...
Hi, I am building a peak detector and voltage comparator for my returning signal of the ultrasonic transducer.
Below are the circuit diagram of peak detector and voltage comparator:
And below are the screenshot of oscilloscope after peak detector and voltage comparator:
As you can see...
Hi, I have recently built a dc-dc converter to convert supply voltage from 6V to 32V, the circuit diagram is as below:
and the circuit on the breadboard is looks like this:
My friend has built one with the same circuit diagram, I have double checked with him, both circuit connects exactly...
The op amp that we are using is LM7171, which is pretty fast, but the thing is we only have single supply here. for the rectifier, we using LM7171, R1=R2=1K, diodes are 1N4007
I am working on a project in which we are trying to design and build an ultrasonic thickness gauge that will calculate the thickness of a given part based on the time difference between sending a signal and receiving a reflection back (using the known speed of sound through the medium).
As we...
