What is the specific working principle? Why does one of the two power-on buffer circuits use so many filter capacitors, while the other only has one? Aren't the bus voltages the same after rectificati...
[i=s] This post was last edited by paulhyde on 2014-9-15 08:57 [/i] I would like to ask the engineer, how to achieve the output impedance of 600 ohms of the preamplifier in question F? Do I need to us...
Why can't the CC2530 timer interrupt flag be cleared? The effect is there, but the interrupt flag cannot be cleared. The code is as follows. [code]#include
