guitar pick-up(microphone used in guitars) as the microphone. We used it because it can be attached to wood‚ here to door so it only get the sound come along the timber without any noise. This microphone doesn’t accept any sound other than sound of knocking. From microphone we get a current signal that is proportional to the energy of the sound wave received by the microphone. Then this signal is send to the signal amplifier. This circuit amplifies the weak signal from microphone so it can be

Some of Peter L Jensen’s accomplishments were the Telegraphone‚ the Loudspeaker‚ and the anti-noise microphone. I know that Peter L Jensen invented the telegraphone because on www.aes.org it says “He began working in the laboratory of Valdemar Poulsen soon after Poulsen’s public demonstration of the telegraphone at the 1900 Paris Exhibition.” This evidence

Input devices 1.Keyboard In computing‚ a keyboard is an input device‚ partially modeled after the typewriter keyboard‚ which uses an arrangement of buttons or keys‚ to act as mechanical levers or electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing and holding several keys simultaneously or in sequence. 2. Mouse In computing‚ a mouse

common devices include microphones‚ radio receivers‚ tape recorders‚ CD players‚ amplifiers‚ AV receivers‚ mixing consoles and speakers. Although these devices can be used by the average Joe‚ the can be put into further use by a sound engineer. A microphone for instance is a device that a live sound engineer would use for setting up a stage performance. Another microphone would be used for a studio engineer setting up the sound booth. The difference is that one microphone is specifically made for
