I designed according to this:
the capacitor-resistor combination will establish the time constant 𝜏, which should be kept to a value above the period of the main component (carrier, 5MHz), but much lower than the modulating signal (in this case dictated by the frequency of repetition 7.8kHz)...
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...
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...
