What is a tuned amplifier?
The tuned amplifier is the type of electronic device designed to amplify the specific range of electrical signals when ignoring or blocking others. They find common use in devices that work with radiofrequency signals such as radios, TVs and other types of communication devices; However, it can also be useful in many other applications. The tuned amplifiers can be found in aircraft autopilot systems, audio systems, scientific instruments, spacecraft or anywhere else when you need to select and amplify specific electronic signals while ignoring others. The FM radio has a tuned amplifier that allows only one radio station to listen to at a time. When the knob is turned to change the station, it adjusts the variable capacitor, inductor or similar device inside the radio, changing the inductive load of the tuned amplifieer circuit. This uniforms the amplifier to enable other specific radio frequencies to reinforce, so you can hear another radio station.
At the same time, all radio communication devices, including stereos, television and mobile phones, accept all signals present in the area. The tuned amplifier in the device is what allows you to amplify only one specific frequency through the process called band filtering. When filtering the band, the electronics are configured to allow only a specific frequency band to pass through the filter. In some devices like FM radio, the filter is adjustable. In other WiFi mobile phones or computer network, the filter is fixed to a single specific frequency range.
Fixed amplifiers tuned to frequency can also be found in sound processing devices such as graphical equalizers. For example, in the five band equalizer, there are five separate controls. Each of these controls manipulates with an individual tuned amplifier. In tOMto is fixed by each of the band filters in tuned amplifiers, allowing a different range of sound frequencies to pass each of the controls. The control of the control for one of these sound frequency strips adjusts the amount of band amplification, not the actual frequency range of the band itself.
tuned amplifiers can have adjustable band filters, adjustable amplifiers, both or neither. The function that identifies the tuned amplifier is that the amplified signals are limited or tuned to a specific range or frequency belt. The ability to configure in so many variations for so much different purposes has made the tuned amplifier to support almost all sophisticated electronic devices that exist.
