Superheterodyne receiver works

Audio, and Armstrong's method is to transform the input signal into super audio, so it is called superheterodyne. In 1919, a superheterodyne receiver was fabricated using the principle of superheterodyne. This kind of receiving method... Making and adjusting the superheterodyne radio_Circuit diagram_radio Figure 3-2 is the block diagram of the working principle of the amplitude modulation superheterodyne radio, the high frequency received by the antenna..The superheterodyne receiver is a radio receiver that utilizes the principle of superheterodyne and was invented in 1918 by American radio engineer Edwin Howard Armstrong. The superheterodyne principle is a mixture of radio waves and extraneous signals generated by a variable oscillator in a machine to generate a fixed frequency intermediate frequency signal (usually the amplitude modulation radio is 450 kHz or 455 thousand...

Servo motor working principle AC servo motor working principle The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electric motor controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field, and the encoder feedback of the motor is provided. Signal to the drive, drive... What is a pressure relief valve and what is the working principle? - Encyclopedia Q & A What is the radio principle is to restore the high-frequency signal received from the antenna to the audio signal through the detection (demodulation), and send it to the earphone to become the sound wave. Due to the development of the broadcasting industry, there are many radio waves of different frequencies in the sky. If you take all of these waves, the audio signal will be like in the middle of the city, many sounds will be mixed together, and you can't hear anything.
