Discriminator Amplitude

Amplitude discriminator: what is it and how does it work?

An amplitude discriminator is an electronic component that is used to distinguish and separate signals by amplitude. It is widely used in various fields including radio communications, television, medicine and scientific research.

The operating principle of the amplitude discriminator is based on the use of nonlinearity of semiconductor diodes. When an alternating voltage is applied to a diode, the current that flows through it has a nonlinear dependence on the amplitude of the input signal. This allows the use of an amplitude discriminator to measure the signal amplitude.

As an example, we can consider the use of an amplitude discriminator in radio communications. When a radio signal arrives at the antenna, it is amplified and fed to the input of the amplitude discriminator. Next, the signal passes through a diode, where its amplitude is measured. If the signal amplitude is above a certain threshold, then the amplitude discriminator generates a signal that is used for further signal processing.

The amplitude discriminator can also be used to detect phase deviations. For example, in medical technology, an amplitude discriminator can be used to measure the force of contraction of a patient's heart. In this case, the amplitude discriminator measures the amplitude of the electrical signal that is generated by the heart and provides information about its strength.

In conclusion, the amplitude discriminator is an important component in various applications where signal amplitude measurement is required. It operates on the basis of the nonlinearity of semiconductor diodes and can be used to detect both amplitude and phase deviations.

Certainly! Discriminatory amplitude converter with manual sound level adjustment. This device allows you to find the difference between two sound signals if the amplitude of one of them is different from the other. The discriminator amplitude module can be used in various fields, for example, in music recording or signal processing for speech transmission. Di

A disciplinary amplification module (amplification discriminator) is a type of discriminatory block. Just like the zero discriminator, it serves to separate the oscillatory process into two oscillations: unstable and stationary. It amplifies and converts alternating voltage into constant or periodically changing without changing its shape and when changing its polarity (that is, it changes the signs of the output voltages).

The type of discriminator largely determines the noise suppression capabilities of the amplifier. If low-frequency noise is suppressed by a transformer and the series capacitance of the coupling capacitor, then high-frequency noise, appearing, for example, on odd side tracks
