What is a common mode amplifier?

I'm not sure there is such a thing as a "common mode amplifier". The common mode rejection ratio (CMRR) of a differential amplifier is very high, and is defined as the ratio of the differential amplification divided by the common mode amplification. The common mode amplification is what you get when both inputs are tied to the same signal. Ideally, this amplification will be zero, but in reality it ends up being some very small amount for well designed amplifiers. This is a beneficial trait for audio equipment which use a positive, negative, and neutral connection (balanced cables, such as microphones). Noise signals will naturally couple to these cables. The assumption is these noise signals will couple nearly identically to both the positive and negative signal wires, so when applied to the amplifier, this common mode signal will not be amplified, while the desired signal (which is created so that the positive and negative signals are opposites) is amplified.


What do you mean by CCMR of an amplifier?

Did you mean CMRR? If so, it stands for Common Mode Rejection Ratio, and it is a measure of how well the amplifier rejects signals that appear on both leads. The idea is that an amplifier should amplify the (Differential Mode) signal, but not any noise (Common Mode) that might appear on the lines, perhaps due to induction from nearby AC power sources. Since induction will show up on both leads, a high CMRR amplifier will have a greater signal to noise ratio overall.If you meant CCMR, please say that in the discussion or the answer, and we can split the question. I don't recognize CCMR.


What does a protection diode do?

It will conduct electricity when the voltage across its terminals reaches a certain value. Once the over voltage is extinguished, the protection diode becomes an open circuit again. Therefore, you need to connect a protection diode between both wires to be protected (differential mode) and from each wire to ground (common mode). Protection diodes are primary protection devices (fast reacting), but they cannot handle too much current. That is why they need to be used with secondary protection devices (fuses and gas arrestors) to provide better protection.

How do you get to the 'secret modes' on a sauce light wand?

Go to the mode with the blinking white light. Press and hold the button. The light will blink faster and faster. Eventually the light will become solid. Keep the button held down. It will change to green and red (Christmas). Keep going and you will get to red white and blue (fourth of Jul).

No you cannot, while in sleep mode it shuts down your networking therefore not allowing you to download however you can turn off your monitor while this process is going on to keep it from going into sleep mode.
