1. A signaling circuit is a type of circuit that is used to transmit information between different parts of a system. One common example of a signaling circuit is found in a telephone system. When you pick up the phone to make a call, the signaling circuit is responsible for transmitting the dial tone, ringing signal, and connecting your call to the intended recipient. In this case, the signaling circuit plays a crucial role in establishing and maintaining communication.
2. A power-limited power supply is a power source that has a built-in limitation on the amount of power it can deliver. This means that the power supply is designed to deliver a specific maximum amount of power, and if that limit is exceeded, it may shut down or provide limited power output to protect the connected devices. On the other hand, a non-power-limited power supply does not have such restrictions and can deliver power without a predefined limit. Non-power-limited power supplies are commonly used in applications where a constant and higher power output is required without the risk of shutdown due to power limitations.
