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.

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.
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.
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.
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.
What is an pulsar for woltman water meter?
It convert the meters mechanical reading to pulses to be transmitted with a radio transmitter

Trace the energy transformations from a radio signal to music you hear?
Electrical to sound.
How did the early radio differ from the early telegraph?
The Telegraph Required Wires The Radio Did Not
What is locating objects by radio pulses?
Radar
How can lighting be a barrier for communication?
Yes, the electrical current running through the ground is enough to dirupt a radio signal.
What does the radar system in Uber self-driving cars do?
Radar emits pulses of radio signal and measures the time of pulses returning back. As the signal is rotated around 360 degrees, an image of the surrounding area is mapped in computer memory. From this, the computer can determine how far objects are, all around and formulate a strategy for avoidance and keeping on track.
What media is used to carry electrical pulses that represents digital data?
Copper cable is the answer. Fiber Optic transmit using light and radio is frequency while wireless is wireless.
What are reasons for electrical interference on car radios?
Electrical interference in a car radio is the same as electrical interference on any radio. Radio interference is literally the sound of the air. When a radio signal is broadcast, the frequency that was previously only occupied by air is overpowered and drowned out, thus you hear the broadcast frequency clearly. When the broadcast frequency is weak (i.e. you are too far away or something is blocking the signal), the frequency cannot completely overpower the air and thus you hear some of both.
