The correct spelling of the word for the device used to receive television signals is "television receiver". The word is spelled phonetically as tɛlɪvɪʒən rɪsivər, with stress on the second syllable in both words. The word "television" is derived from "tele-" meaning "far off" and "vision" meaning "to see", while "receiver" means "a device that receives and converts signals into a form understandable by humans." Correct spelling of words is important for clear communication and effective writing.
A television receiver is an electronic device that is used to capture and display broadcasted television signals. It is commonly called a television (TV) or television set. A television receiver is primarily designed to receive over-the-air television signals transmitted via radio waves, although it can also receive cable or satellite signals.
The television receiver consists of various components including a tuner, which selects the desired television channel, and a demodulator, which extracts the audio and video signals from the received signal. These audio and video signals are then processed by other circuits within the TV set, such as an audio amplifier and a video display unit.
The display unit of a television receiver is typically a cathode ray tube (CRT) or a more modern liquid crystal display (LCD) or organic light-emitting diode (OLED) panel. The video signal is converted into a series of lines and pixels, which are illuminated on the screen to create a visual display. The audio signal, on the other hand, is amplified and outputted through built-in speakers or external audio devices.
Television receivers also come with various features and options, such as remote controls, built-in digital tuners, HDMI ports for connecting external devices, and access to Smart TV functionalities, allowing users to stream online content, browse the internet, and access multimedia applications.
The etymology of the word "television receiver" can be traced back to the roots of its individual components.
1. Television: The word "television" is a combination of the Greek word "tele" meaning "far" and the Latin word "visio" meaning "sight". It was coined by Russian scientist Constantin Perskyi in a paper presented at the International Electricity Congress in 1900. The term was used to describe the transmission and reception of images over long distances.
2. Receiver: The word "receiver" comes from the Latin word "recipere", which means "to receive". It is a noun form of the verb "recipio", referring to the action of taking or accepting something. In the context of electronics, a receiver is a device that receives and processes signals or transmissions.
