SpletConstruct the circuitry shown in Figure 5 on a solderless breadboard. Use the 1N914 fast switching diode for the diode ring. Set W1 as a 1kHz sine modulating signal with 1V amplitude peak-to-peak and set W2 as a 10kHz sine carrier with a 3V amplitude peak-to-peak. For the input and output transformers, a 1:2 turns ratio is needed. The mixer circuit can be used not only to shift the frequency of an input signal as in a receiver, but also as a product detector, modulator, phase detector or frequency multiplier. For example, a communications receiver might contain two mixer stages for conversion of the input signal to an intermediate frequency … Prikaži več 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 … Prikaži več • Electronics portal • Frequency multiplier • Subharmonic mixer • Product detector Prikaži več The essential characteristic of a mixer is that it produces a component in its output which is the product of the two input signals.

Splet14. jan. 2024 · A frequency mixer that functions through switching uses a smaller input signal and passes it either inverted or non-inverted per the phase of the LO. Furthermore, operationally, this is the equivalent to a packaged double-balanced mixer, since the LO drive is significantly higher than the signal amplitude. SpletWe define mixer an electronic circuit that gives as output signal the product of two input signals v t1 and v t2 (). In other words the output signal can be expressed as v t K v t v tout m()= 1 2()(), where Km is a real (non – zero) constant. The schematic symbol of this component is shown in figure 1.
