In telecommunications, squelch is a circuit function that acts to suppress the audio (or video) output of a receiver in the absence of a sufficiently strong desired input signal. carrier squelch is unlocked and will let any signal in. Selective calling locks out all signals except ones with the correct code. In non-critical uses, selective calling can also be used to hide the presence of interfering signals such as receiver-produced intermodulation.
Look after your eyes Â» Eye conditions Â» Squint. Squint (also known as strabismus) is a condition that arises because of an incorrect balance of the muscles that move the eye, faulty nerve signals to the eye muscles and focusing faults (usually long sight). This can happen in either eye and the misalignment can be in any direction. 2  A squint may occur for a number of reasons. 3  Sometimes, one or more of the muscles that move the eyes is in the wrong place. 4  Sometimes the muscles do not work as they should.
