Final answer:
A sinking circuit is used to pass digital information to the next device in digital circuits by providing a low impedance path for the current to flow.
Step-by-step explanation:
In digital circuits, a sinking circuit is used to pass digital information to the next device. It works by connecting the output of one device to the input of the next device through a low impedance path. This allows a high current to flow from the output device to the input device, effectively sinking or drawing away the digital signal.
For example, let's consider a simple digital circuit connecting two devices. When the output device sends a digital signal, the sinking circuit provides a low impedance path for the current to flow towards the input device. This allows the input device to detect and interpret the digital signal accurately.
Overall, the sinking circuit in digital circuits ensures efficient transfer of digital information between devices by providing a reliable and low impedance path for the current to flow.
