The superheterodyne radio receiver, or last name, first name, to give it a super heterodyne receiver, STI is one of the most popular forms of the receiver is used today in various applications of radio receivers passed for bilateral communication lines, as well as many mobile radio communication systems.
Although other forms of radio receiver is used, the receiver supergeterodinnogo is one of the most commonly used forms. Although Initially developed in the early days of radio or wireless technology, at supergeterodinnogo supergeterodinnoj or receiver offers significant advantages in many applications. Naturally the main concept, developed from the first days it was rather more complex and challenging version uses, but the basic concept remains the same.
History of the Superheterodyne receiver
This form of the receiver is based on the idea of mixing the signals in a non-linear way. This idea was first noticed when bits were discovered between two signals. RA Fessenden was the first who noticed this and he patented the idea in the year 1901.
However, the idea lay dormant for many years, since most receivers Some consisted of detectors and tuned circuits. termoèlektronnoj Diode valve or vacuum tube Ambrose Fleming was invented in 1904, and the third grid then add Lee de forest. Although early valves or used pipes, they were very unstable and difficult to get much Boo Useful performance from them.
A young engineer by the name of Edwin Armstrong Began to use the power of termoèlektronnoj valve or vacuum tube, inventing a regenerative receiver around 1910 provided substantial useful gain increase over what was previously achieved.
This was the beginning of the great war in 1914, which gave new impetus to the development of radio. There was a requirement for sensitive radio receivers for a variety of tasks. the first major step was made of a Frenchman named Lucien levy. At that time, the performance of the valves was very poor at frequencies above 100 kHz or so, and It has developed a system to reduce the frequency of the incoming signal, using the system blows-signal can then be customized and enhanced more effectively at lower frequency.
Edwin Armstrong Chamber to the fore again, in supergeterodinnoj or supergeterodinnogo receiver develops as we know it today with a fixed intermediate frequency filter and variable frequency oscillator of the local. It was designed in 1918, at the very end of the war, and as a result, it has not been used widely.
After the war, BU Discovered postulated receivers like Germans, but none were actually made. As a result, Edwin Armstrong was credited with the invention.
The receiver is not used originally supergeterodinnogo, BU I felt that many of the valves do not contribute to the complete signal amplification, and valves were expensive. However, as the number of TV stations and an increase in selectivity was the year of issue, along with the falling value of vacuum tubes, using receiver supergeterodinnoj began in the late 1920 's to grow and in the early 1930 's. Since then it has been in Widespread use.
Notes on the history of radio: supergeterodinnoj
The superheterodyne radio receiver, or use its full name, the superheterodyne radio receiver was developed during World War I. The development of many of the Arosa above performance both in terms of the selectivity and sensitivity. However, additional valves (tubes) used meant that he did not use the more common prior to the 1930 year does not become cheaper if technology required performance levels and this is when it became a necessity.
