frequency mixer

The analog phase detector takes the form of an ideal frequency mixer.

The circuit usually consists of a local oscillator and frequency mixer.

Other frequency components may also be produced in a practical frequency mixer.

The non-linearity of the superparamagnetic material acts like a frequency mixer.

This signal is applied to a frequency mixer.

Now as the frequency mixer has fewer outputs the task of making sure that the final output is clean will be simpler.

Each of these peaks can potentially Frequency mixer with some other incoming signal and produce a 'spurious' response.

A product detector is a frequency mixer.

The highly non-linear characteristics of tunnel diodes makes them useful as frequency mixers.

See frequency mixers, to read further about carrier leakage or local oscillator feedthrough.

The classic frequency mixer is a multiplier.

Frequency mixers are also used to modulate a carrier frequency in radio transmitters.

The system also permitted the audio signal to be scrambled by inverting its spectrum at 12.5 kHz using a frequency mixer.

The frequency mixer was of the pentagrid converter design to save the cost of a separate oscillator tube.

Similar examples could be created for any of the 'ideal' circuit elements listed above, and many more, from RF frequency mixers to the simplest switch.

It is also used in electrical engineering to model intermodulation distortion in many devices including power amplifiers and frequency mixers.

In electronics a mixer or frequency mixer is a nonlinear electrical circuit that creates new frequencies from two signals applied to it.

The direct-conversion receiver feeds the radio frequency signal into a frequency mixer, just as in a superheterodyne receiver.

They are key components in many electronic devices, particularly radio equipment, used in circuits such as oscillators, filters, tuners and frequency mixers.

Also, the animation contains both up- and down-converted spectra, which is due to a frequency mixer producing both sum and difference frequencies.

Nonlinear distortion applied to a superposition of two signals at different frequencies causes the circuit to act as a frequency mixer, creating intermodulation distortion.

For instance, the frequency mixer produces harmonics that adds complexity in applications where spectral purity of the VCO signal is important.

The harmonic mixer and subharmonic mixer are a type of frequency mixer, which is a circuit that changes one signal frequency to another.

The scrambling of the audio signal was not a cryptographically controlled process and could easily be undone using the same frequency mixer circuit used for scrambling.

Determination of a third-order intercept point of a superheterodyne receiver is accomplished by using two test frequencies that fall within the first intermediate frequency mixer passband.
