Questions tagged [wien-bridge]

Anything related to Wien bridge circuits. A Wien bridge is a particular bridge circuit configuration in which two sides of the bridge are purely resistive, whereas the other two are made up by resistors in parallel with capacitors. Wien bridges are commonly used in linear oscillators for producing sinusoidal signals.
