As shown in the picture, when I change the voltage, the current remains unchanged, but when I change the resistance of R2, the current changes. Why is that?...
[i=s]This post was last edited by paulhyde on 2014-9-15 03:19[/i] We used the 90M bandwidth schematic in the manual in the process of making the amplifier gain. We first tested the single-stage amplif...
For example, in the picture, what does B00,0x38f7 mean? What does 124507 mean? LCALL is the assembly language long call, and the following C:4507 is an address, right?
But what does C: mean?...
