Electronic discriminators are a type of electronic circuit used to distinguish between signals that are all within the same frequency range. They are typically used to separate out signals from noisy environments or to filter out undesired signals from a desired signal.

An electronic discriminator is an analog circuit that utilizes several components, such as resistors, capacitors and transistors. The circuit is designed to produce an output voltage that is proportional to a difference between the input voltages. This allows the discriminator to separate out signals of a specific frequency from all other signals within the same frequency range.

The most common use of an electronic discriminator is to separate out audio signals from a microphone from other noise in a room. Electronic discriminators can also be used to filter out undesired frequencies in an audio signal. This can be done either before or after the signal is digitized.

An electronic discriminator is also used in radio reception. It is used to separate the desired signal from interfering signals that are within the same frequency range. This allows radio receivers to receive and process the desired signal without interference from other sources.

Electronic discriminators can also be used to separate two signals that are not of the same frequency. This is done by sequentially changing the coefficients of the discriminator until the desired signal is distinguished from all other signals.

In conclusion, electronic discriminators are an important component of many systems and have a wide range of applications. They can be used to remove unwanted noise from audio signals and to separate out signals from noisy environments. They can also be used to distinguish between signals of different frequencies.
