rdfs:comment """In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals V_+ and V_- and one binary digital output V_\text{o}. The output is ideally
\begin{cases}
1, & \text{if }V_+ > V_-, \\
0, & \text{if }V_+ < V_-.
\end{cases}
A comparator consists of a specialized high-gain differential amplifier. They are commonly used in devices that measure and digitize analog signals, such as analog-to-digital converters (ADCs), as well as relaxation oscillators.
