... 4.0 FM Optical Link: In experiment #6, you will build an FM optical link using the Agilent 3316 LED and a Radio-Shack phototransistor. The transmit portion of the link is composed of the LM 566C voltage-to-frequency converter with a triangular output waveform. The center frequency is set to 100 KHz. ...

... In the interest of time, the receiver is build for you. This will let you concentrate on measuring the performance of the receiver and on listening to FM music. The phototransistor has a 1 KΩ load and therefore a cutoff frequency of around 10 KHz. The phototransistor therefore acts as a low pass fil ...

Telecommunication



Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs. Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, and loud whistles. Modern technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, and communications satellites.A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909. Other highly notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Charles Wheatstone and Samuel Morse (telegraph), Alexander Graham Bell (telephone), Edwin Armstrong, and Lee de Forest (radio), as well as John Logie Baird and Philo Farnsworth (television).
