A nolinear circuit that produces an output at the sum and difference frequencies of an applied fixed or variable oscillator called the LO, and the RF input signal of interest (see Heterodyne)
A device in which two or more input signals are combined to give a single output signal In satellite communication systems, it is a non-linear device used to generate a replica of an input signal at a higher or lower frequency by multiplying the input signal by a pure tone of a different frequency (the "local oscillator" signal) Usually part of a frequency conversion process For example, an LNB local oscillator signal at 10 6 GHz mixed with incoming signal at 12 GHz would convert the input signal to an IF frequency of 12 -10 6 = 1 4 GHz
A mixer is a piece of equipment that is used to make changes to recorded music or film. a three channel audio mixer
A light pocket hit that scatters the pins resulting in a strike A ball with a lot of action
A device for summing two or more electrical signals In general audio usage, a device to control and sum the outputs of two or more microphones In wireless microphones, the receiver circuit which mixes the RF signal with the local oscillator signal to obtain the IF output
A nonlinear circuit or device that accepts as its input two different frequencies and presents at its output (a) a signal equal in frequency to the sum of the frequencies of the input signals, (b) a signal equal in frequency to the difference between the frequencies of the input signals, and, if they are not filtered out, (c) the original input frequencies
A person who has social intercourse with others of many sorts; a person viewed as to his casual sociability; commonly used with some characterizing adjective; as, a good mixer; a bad mixer
A device that connects and routes all the input and output signals from one component to another Mixing boards also have signal-processing capabilities such as equalization and reverb Mixers save you from the hassle of patching together different pieces of equipment for common, day-to-day studio tasks
a recording device that allows several different audio sources to be combined Provides independent control over each signal's loudness and stereo position
The piece of equipment that takes the different sources of audio and blends them together to get a final sound from all sources of sound at once
a device that will "mix" the input signals together producing the two original signals and their sum and difference frequencies
A desk comprising a number of input channels where each sound source is provided with its own control channel through which sound signals are routed into two or more outputs Many mixing desks can also change the quality of the sound (see Equalization) A Powered Mixer has an amplifier built into it Sound sources of varying levels are accepted which can be amplified if necessary (See Line Level, Gain) NOISE GATE : A piece of sound processing equipment that reduces background noise by muting a sound signal when it falls below a certain level, restoring it when the level increases again Must be used on vocal microphones with care, because it may cut the signal off, although the vocalist is still singing quietly Also known as an Expander
The critical element of a radio detection system which allows the incoming wave to be combined with the reference frequency from the local oscillator Usually a diode
a kitchen utensil that is used for mixing foods electronic equipment that mixes two or more input signals to give a single output signal club soda or fruit juice used to mix with alcohol
A device which utilizes its non-linear characteristics to provide frequency conversions from one frequency to another This may be from a relatively high frequency to an intermediate frequency (IF) In this case it is known as a down-mixer Or it may be from a lower frequency to a higher frequency, the carrier frequency, for example In this case it is known as an upmixer
A mixer is a machine used for mixing things together. an electric mixer. see also cement mixer, food mixer
An audio or video processor that combines two or more source signals in an output signal Separate controls typically permit tone and volume control over the contribution of each source signal to achieve an optimum tone balance
