How can i convert -20V into dB? |
| magic:
You can't, logarithm is only defined on positive numbers. Decibel scale is usually used to refer to signal power and power is always positive too. It's you the Decibel Guy again, I see. You would get more sensible responses if you explained what you are trying to calculate and why instead of asking one-liner questions that don't even have a valid answer. |

The question is what is the voltage gain of the transistor in dB? its -20V! I need to convert that to dB |
| Kalin:
No it is not -20V. People are not going to do your homework for you. If you want to know how something works or where you went wrong in a calculation many people will help you, but noone is going to just give you answers. Gain is a ratio of input to output and doesn't have a unit. Sent from my SM-G965W using Tapatalk |

I dont ask for answers just for good advice on how to solve the task.Instead of saying u are not doing my homework which i dont want, u can tell me why -20V is wrong. Ua=20Vss and Uce=Ua. UCE is the voltage gain of the transistor. So why its wrong. |
