Changing sound waves into electromagnetic signals is the basic function of a microphone. The electromagnetic signal may be sent through a wire or broadcast as an electromagnetic wave such as a radio wave.

Sound waves are gathered by a thin material that vibrates when the sound hits it (microphone) - The material has a magnet attached on the back surrounded by a coil of wire. The magnet vibrates inside the coil and creates a voltage/current in the coil. Wires from the coil are connected to an antenna which is a special shaped conductor. The current moving up & down in the antenna creates EM waves which radiate out into space. This is the basic idea. The actual circuit will have an amplifier to increase the electricity, from the coil, before sending it to the antenna.

What is the Cost of pneumatic control valve product?

Pneumatic process control valves are used in process industries to control the flow of fluid by using pneumatic actuators. It requires 4.5 to 6 Kg/sq. cm of pressure to operate the valve. Control room sends electrical signals of 4-20 ma to field where I/P converter converts these electrical signals into pneumatic signals. Actuators use these signals to operate the valve. Actuators moves the stem up and down depending upon input signals and control the valve opening. 4ma- 0% opening 8ma- 25% opening 12ma- 50% opening 16ma- 75% opening 20ma- 100% opening


What does a Futaba transmitter do?

A Futaba transmitter sends signals over a frequency to a receiver. It comes with a 2.4GHz frequency technology that makes a radio controlled vehicle reach maximum performance wireless and provide better precision on track or on air.


What technique has been used in designing electronic surveying instruments?

Electronic surveying instruments are designed by a common technique. When electronically determining the straight-line distance between two points or stations, we use equipment that sends an electronic. Impulse of known velocity or rate of speed and measures the time it takes for the impulse to travel the length of the interval between the points. Then, by using the well-known equation of distance, Distance = rate × time The length of the interval is determined.


How do you use a circuit breaker finder?

My unit requires you to plug in the tone generator to the outlet whose corresponding breaker you are trying to locate and turn on the tone. You then go to panel with receiver and hold button in while running the receiver up and down the panel. You will hear a tone once the breaker is located.


What is multiplexer?

Multiplexing is the ability of a number of devices to share a transmission facility.If each device needs the facility only a fraction of time,then the sharing arrangement allows the cost of the facility to be spread over many users. post by Mohammed Alkhattab quote from William Stallings book

Is it true or false that epithelial tissue sends electrical signals throughout the body?

False. Epithelial tissue does not send electrical signals throughout the body. Epithelial tissue is responsible for lining and protecting various organs and structures, but it does not have the ability to generate or transmit electrical signals. Electrical signals in the body are primarily sent by specialized cells such as neurons.
