Audio and high fidelity audio receivers, satellite television receivers, and crystal radio receivers or radio sets are some of the most common and popular forms of radio receivers in the market today. All these equipment are generally known as radio receiver. Radio receivers are defined electronic circuits that act as detector, demodulator and amplifier of transmitted signals. These signals are then being transformed into usable form such as sound, pictures, digital data, measurement values, navigational positions, etc.
An AV receiver is a type of receiver which uses an amplifier, a preamp/processor, and an FM/AM tuner. Along with audio and high fidelity audio receivers, this type of receiver is the most commonly used type especially by home stereo listeners and audio and home theatre system enthusiasts. The increased need in better audio is brought about by the increasing number of high definition television and home theatre systems found in the market. On the other hand, there are also the satellite television receivers which can be considered as the most widely used radio receiver in the world today. This type of radio receivers is used to receive television programming from communication satellite found din the outer space. Given the fact that almost all homes in the world have at least one television set at home, it is no wonder that this type are the most popular and widely used.
Used in the reception of modulated AM/FM signals, crystal radio receivers or radio sets as they are commonly known are considered as the simplest type of radio receiver. The first example of this radio sets are the transistor radios popular during the early 1900's. These days, AM and FM radios are being integrated as parts of more common music and sound sources which includes cassette players, DVD/CD players, MP3 CD, USB key players. Other popular types of radio receivers include the communications receivers, specialized-used receivers, measuring receivers, and scanners. All these types of radio receivers are commonly used fro the purpose of entertainment. However, it is also important to note, that besides entertainment, these are also being used as tools fro business as well as security purposes.
The discovery of the electromagnetic waves in the 1850's by James Clerk Maxwell is the initial step the invention of radio receivers. Heinrich Hertz in 1887 demonstrated how electromagnetic waves work through the use of a spark gap equipment to transmit and receive radio waves. Alexander Stepanovich Popov on the other hand, was the one who designed the first ever radio receiver which was fir seen by the public eye in the All Russia Exhibition in 1896. Popov showed through an experiment how a wireless device is able to detect an electromagnetic signal through the air and can convert this into usable form just like the ways our mobile phones nowadays work.
Radio receiver technology in the present continuously moves forward. Receiver technology has improved greatly from the discovery of electromagnetic waves to the discovery of transistors and radio sets. Nowadays, this technology continues to move gradually but regularly. Converting signal to digital stream manipulated mathematically is now widespread and is popularly known as Digital signal processing. Different soft wares are also being used in order to be able to do other functions which are normally performed by an analogue intermediate frequency stage.
Radio receivers have indeed been a great leap in the field of science and technology. With these receivers, communication and entertainment have been made easier for consumers. From transistors, radio sets, television sets and today, cellphones, radio receivers have been a vital part in the search for ways on how to improve every individual's day-to-day living.
