When I was making an amplifier, I found that there was high-frequency interference when the amplification factor was large, but I couldn't filter it out with a low-pass filter. Because the bandwidth r
statement:This USBISP is made based on an open source design from a German on the Internet ( http://www.ullihome.de/index.php/USBAVR-ISP ).
I only made a few changes to the hardware. I have made more
Looking through the whole book, it is nothing more than transistor amplifier circuits, field tube amplifier circuits, negative feedback amplifier circuits, integrated operational amplifiers, waveforms
