Your question is quite incomplete.
If you want to convert a PwM (pulse width modulated) infrared signal, just pass on the width info to a fixed carrier wave (amplitude modulate it), and the job is done.
At the other end, demodulate using standard If stage as in any superheterodyne radio reciever.
What else can I help you with?
How can you convert the digital signal given on the speedometer in the car into radio waves which can be received some where else?
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
What is a RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
Discussion about amplitude demodulator?
A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination. For many years the modulated carrier wave was converted to a radio signal. Now it is often an electrical signal which is sent down a teleohone line; the information is usually a set of pulses going between computers. When computers are connected to each other in a two-way conversation, the MOdulator and DEModulator are combined into a single device called a MODEM.
Can you have a radio signal underground?
Yes, you can however the distance that a signal may be travel depends on the power and frequency of the signal. For signals at the same power a lower frequency signal will travel further.
How do you generate an oscillator signal?
An oscillator is an electronic circuit that produces an electronic wave or signal. The oscillator signal is the signal the oscillator puts out. An oscillator can put out different frequencies and different types of waves depending on how it is designed. These signals have many different uses in electronics. For instance you can use it to convert DC (direct current) from a battery to 60 Hz AC (alternating current) to use in a home. Some oscillators are variable like what you have in your radio or TV for picking up different signals or stations. To produce an oscillator signal: if you know a lot about electronics you can build your own from parts you can get at some place like Radio Shack. Otherwise you can buy an oscillator. Radio Shack might have one or you might have to look on line. You also have to know what kind of wave and frequency you need to be sure and get an oscillator that produces that signal. If the signal you need is unusual you may need a variable oscillator.
What do am radios convert sound into?
AM transmitters convert sound into amplitude modulated radio waves which am radios convert into electrical pulses which speakers convert into air waves that are converted into sound by our eardrum.
How do you convert the factory radio to get Sirius?
You cannot convert a standard radio to receive the satellite radio signal. You will have to purchase a Sirius satellite receiver.
How does a radio signal go from a disc jockey speaking into a microphone at a radio station to your ear?
In the microphone, there is a diaphragm, which converts the DJ's voice into an electrical signal. This signal is sent along the wire to the antenna, which broadcasts it into the ether. Your home radio receives the signal through its aerial, then converts the signal from an electrical signal to audio - which is detected by your ear.
Trace the energy transformations from a radio signal to music you hear?
Electrical to sound.
What has to happen to sound wave before they can be transmitted by radiowaves?
Sound waves need to be converted into electrical signals before they can be transmitted by radio waves. This is typically done by using a microphone to capture the sound waves and convert them into electrical signals that can then be modulated onto a radio frequency carrier wave for transmission.
What is an pulsar for woltman water meter?
It convert the meters mechanical reading to pulses to be transmitted with a radio transmitter

What electromagnetic wave does a microphone use?
A microphone uses sound waves, which are mechanical waves, to convert sound into an electrical signal. This electrical signal can then be amplified and transmitted. Electromagnetic waves, such as radio waves or light waves, are not used directly by a microphone in this process.
Can you use an amplifier circuit to convert sound energy into electrical energy?
No. Power can't be amplified, because to do so would require the creation ofenergy, which is always a no-no. However, a circuit with small power can beused to control a circuit with large power derived from somewhere else. Soif you can maintain sufficient power-input to the high side, the whole operationhas the appearance of having amplified the low power. The best example of thatprocess is any radio receiver.
What is locating objects by radio pulses?
Radar
What type of energy transformation does a radio signal have?
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
How did the early radio differ from the early telegraph?
The Telegraph Required Wires The Radio Did Not
