Figure 2 Finding the loop gain T of the circuit of Figure 1 via (a) return-ratio analysis, and (b) by breaking the loop and properly terminating it at the return side.. Return-ratio analysis requires ...

An electrical circuit is a loop through which an electric current close electric current The flow of electricity through a wire or circuit. can flow. It consists of: a power source – such as a ...

This circuit is a low-cost alternative that provides not only a 4- to 20-mA output, but also a digital feedback signal that indicates an open wire in the current loop (Figure 1). One output-port pin ...
