A Wireless Device works without using cables to communicate.

Extracts from this document...


Introduction: A Wireless Device works without using cables to communicate. Everything is based on the antenna. The antenna is the main electronic part of the device. It is used for transmitting a radio signal to a receiver and translates it back to an audio signal, which human beings can understand. It includes three main components: an input device, transmitter, and a receiver. The input device can be a guitar, microphone or audio system. The idea of this wireless device is to be able to send radio signals from the input device to the transmitter where the transmitter then sends translated radio signals to the receiver as an audio signal. In the final stage, the receiver receives the signal from the transmitter and transfers the entire audio signal to the speaker where we can hear. Descriptions of Parts and their Function Input Device: A guitar as the input device requires magnets and coil to produce sound. ...read more.


The second process is to compress the audio signal with in a limited dynamic range of a radio transmission. Finally, the transmitter then sends an audio signal to the receiver through the frequency multiplier. Moreover, wireless transmitters come in three different forms: body pack, handheld, and plug-on. Receiver: Receivers are available in two kinds known as fixed and portable. The basic idea of a receiver is to pick up the radio signal that was transmitted from a transmitter and convert it to an audio signal. The receiver comes with a built in antenna that can detect signals coming as a radio signal. The first step of the receiver is to reject unwanted radio signals from the transmitter. The second step of the receiver is to generate a constant radio signal using the Local Oscillator. Finally, the receiver will detect the audio signal from the transmitter and send the audio signal to the mixer. ...read more.


The magnet is connected to the coil with negative and positive wires to produce an electric field. With enough electric field the coil will start to move up and down in the air and create sound waves. Basic Operation As shown in figure 1, a guitar as an input device connects to the transmitter to send an audio signal. A transmitter that requires a 9volt battery will then transmit the audio signal to the receiver as a radio signal. The antenna is the part of the transmitter that sends the audio signal to the receiver. The receiver will receive the radio signal from the transmitter and then convert it back to an audio signal. Finally, the receiver will now send an audio signal to the mixer where the mixer sends the final audio signal to the speaker. The speaker then produces sound where we can understand. Sound Output Figure 1 Flow Chart for Wireless Device Operation Conclusion This wireless device will eliminate the use of cables to connect to the sound system. It means musicians have more freedom to move around on the stage. ...read more.
