Which of these can be used as detector diodes?
Types of detector diodes Diodes used in detectors can be Schottky or Esaki tunnel diodes. The two ports of a detector are the RF port and the video port.
What is the function of a detector?
In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage.
What is the working principle of metal detector?
The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. The single-coil detector illustrated below is a simplified version of one used in a real metal detector.
What is difference between demodulator and detector?
A detector is a device that recovers data of interest from a modulated wave. A demodulator is a circuit that is used in amplitude modulation and frequency modulation receivers to separate the information that was modulated onto the carrier from the carrier itself.
What is the function of diode detector circuit?
A diode detector is an electrical component that is commonly used in radio receiver circuits. These tools are also known as semiconductor diode detectors, and they regulate the passing of electrical currents . With a diode detector installed, impulses will be restricted from passing in the reverse direction, and will pass only in the forward direction.
What is a circuit detector?
A circuit detector is a device that completes electrical circuits in order to locate and diagnose electrical paths. The basis for this technology is used for many electrical systems and related tools, including the location of open or short circuits with signal tracers or voltage detectors,…
What is an envelope detector?
An envelope detector is an electronic circuit that takes a high-frequency signal as input and provides an output which is the envelope of the original signal. (ω c » ω m)
