Question 1. What are microphones? State its types.
A microphone is a type of transducer which is responsible for converting the acoustic energy into electric energy. There are two types of microphones: Dynamic microphones and Condenser microphones.
These are also called as a moving-coil mic. These microphones are constructed simply and are economical. This type of microphones does not require any battery or power supply for carrying out its operations.
These are also called as a capacitor. The construction of these microphones is complex and costly. The functioning of these microphones requires a battery or power supply. These microphones are affected by extreme temperature and humidity.
Question 2. What do you understand by speakers?
Speaker is a type of electromechanical transducer which is responsible for converting an electrical signal into sound. Devices or drivers those who consist of an enclosure incorporating one or more drivers can be termed as speakers or loudspeakers. A number of drivers are present in a speaker which are responsible for reproducing a wide range of frequencies for high sound pressure level. In a speaker, there are subwoofers for very low frequencies, woofers for low frequencies, squawkers for middle frequencies, tweeters for high frequencies and super tweeters for very high frequencies.
Question 3. What do you understand by a TV transmitter?
A television transmitter is a kind of transmitter which can be used for terrestrial television broadcasting. It is an electronic device which is responsible for radiating radio waves carrying a video signal along with a synchronized audio channel, which is received by the receivers of television that belongs to the audience and this is how the image is displayed on the TV screen. A television transmitter when operates with a broadcast studio is known as a television station. A television transmitter must be licensed by the government to start its operation.
Question 4. Explain positive and negative modulation in TV
When an increase in brightness of picture produces an increase in the amplitude of the modulated envelope, then it is called a positive modulation.
When an increase in brightness of picture produces a decrease in amplitude of modulated envelope, then it is called a negative modulation.
