Mixed signal integrated circuit: the metal areas on the right-hand side are capacitors, on top of which are large output transistors; the left-hand side is occupied by the digital logic. A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die.
Frequency mixer symbol. In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it.In its most common application, two signals are applied to a mixer, and it produces new signals at the sum and difference of the original frequencies.
Source separation, blind signal separation (BSS) or blind source separation, is the separation of a set of source signals from a set of mixed signals, without the aid of information (or with very little information) about the source signals or the mixing process.
An electronic circuit can usually be categorized as an analog circuit, a digital circuit, or a mixed-signal circuit (a combination of analog circuits and digital circuits). The most widely used semiconductor device in electronic circuits is the MOSFET (metal–oxide–semiconductor field-effect transistor ).
When the two signals are mixed, a "beat" frequency equal to the difference between the two frequencies is created. Adjusting the local oscillator frequency correctly puts the beat frequency in the audio range, where it can be heard as a tone in the receiver's earphones whenever the transmitter signal is present.
Investors face mixed signals from Wall Street — as well as a historical calendar that suggests some chop might be around the corner.
Gilbert cell mixers are an arrangement of transistors that multiplies the two signals. Switching mixers use arrays of field-effect transistors or vacuum tubes. These are used as electronic switches, to alternate the signal direction. They are controlled by the signal being mixed. They are especially popular with digitally controlled radios.
China’s vast manufacturing industry sent mixed signals last month about the health of the economy, fueling calls for Beijing to do more to boost growth just days before a key meeting of the ...
