A signaling circuit is a system that transmits information from one point to another. One example of a signaling circuit is a telephone system. In a telephone system, when you speak into the phone, your voice is converted into electrical signals that travel through the phone line to the receiver, where they are converted back into sound.
A power-limited power supply is a type of power supply that is restricted in the amount of power it can deliver. This limitation is designed to protect the connected devices from receiving too much power, which could damage them. An example of a power-limited power supply is the USB port on a computer, which has a limited power output to prevent overloading connected devices like smartphones or external hard drives.
On the other hand, a non-power-limited power supply does not have restrictions on the amount of power it can deliver. This means it can supply a higher amount of power compared to a power-limited power supply. An example of a non-power-limited power supply is a generator used to power large machinery or appliances in a factory, as it can deliver high amounts of power without limitations.
