Hi:

Does a device that performs the following conversions and modulations
exist? If not, is it possible to construct?

Prior to being superimposed on a carrier wave, a modulator signal has
its alternating-current converted to direct-current of the same
frequency, amperage, voltage, and wattage.

What I mean by this is that before this AC-to-DC conversion, if
graphed, the current will be seen going up from the x-axis [zero] to
its peak, then down to x-axis, then below the x-axis to its negative
peak, then back up to the x-axis. Both the positive and negative peaks
are of equal distant from the x-axis. This is an AC cycle.

After AC-DC conversion, if graphed the current goes from the x-axis to
it’s peak, then down to the x-axis, then back up to it’s peak and then
down to the x-axis again. As you can see, there is no longer any
negative polarity. It goes from 0 to peak to 0 repeats. This is a DC
cycle. Once again, both peaks are equally distant from the x-axis.

After this is when the modulation occurs.

During modulation, the carrier wave [also a DC current because it
never goes below the x-axis] is affected by the modulator wave. The
carrier’s base frequency is zero Hz and its base amplitude is zero
watts-per-square-meter.

Base = without modulation

When the modulator signal’s frequency increases, the peak-to-peak
amplitude of the carrier signal increases equivalent to the following
manner: In numbers, the peak-to-peak amplitude [in watts-per-square-
meter] of the carrier signal equates to the frequency of the modulator
signal [Hz]

When the modulator signal’s frequency decreases, the peak-to-peak
amplitude of the carrier signal decreases equivalent to the following
manner: In numbers, the peak-to-peak amplitude [in watts-per-square-
meter] of the carrier signal equates to the frequency of the modulator
signal [Hz]

When the modulator signal’s peak-to-peak amplitude increases, the
carrier’s frequency increases such that – in numbers – the frequency
of the carrier wave [in Hz] equates to the amplitude [in watts-per-
square-meter] of the modulator wave.

When the modulator signal’s peak-to-peak amplitude decreases, the
carrier’s frequency decreases such that – in numbers – the frequency
of the carrier wave [in Hz] equates to the amplitude [in watts-per-
square-meter] of the modulator wave.

During demodulation:
When the carrier signal’s frequency increases, the peak-to-peak
amplitude of the demodulated modulator signal increases equivalent to
the following manner: In numbers, the peak-to-peak amplitude [in watts-
per-square-meter] of the demodulated modulator signal equates to the
frequency of the carrier signal [Hz].

When the carrier signal’s frequency decreases, the peak-to-peak
amplitude of the demodulated modulator signal decreases equivalent to
the following manner: In numbers, the peak-to-peak amplitude [in watts-
per-square-meter] of the demodulated modulator signal equates to the
frequency of the carrier signal [Hz].

When the carrier signal’s peak-to-peak amplitude increases, the
demodulated modulator signal’s frequency increases such that – in
numbers – the frequency of the demodulated modulator wave [in Hz]
equates to the amplitude [in watts-per-square-meter] of the carrier
wave

When the carrier signal’s peak-to-peak amplitude decreases, the
demodulated modulator signal’s frequency decreases such that – in
numbers – the frequency of the demodulated modulator wave [in Hz]
equates to the amplitude [in watts-per-square-meter] of the carrier
wave

You appear to be describing voltage-to-frequency conversion (V2F) and
its inverse, frequency-to-voltage conversion (F2V). Your modulator
seems to perform both functions simultaneously - the frequency and
amplitude of an input signal are encoded as the amplitude and
frequency (respectively) of an output signal. The demodulator is just
the opposite, which you might achieve by just exchanging the
connections to a second "modulator".

There are many ways to do this in practice. Why do you ask?

Since direct current by defintion has no frequency, what you're asking
for is not just impossible, the question makes no sense.

I think this device would be useful in generating a higher frequency
signal from a bunch of lower frequency signals.

For example, achieving a 10 Hz signal from ten 1 Hz signals.

THey call that a V TO F, F to V,. V = Voltage, Frequency.
Click to expand...

what you described is a Frequency to Voltage, and Back to
Voltage to Frequency..

Both exist in the industrial world for doing things like converting
encoder signals to analog and the other way.

In the basic electronics, there are various ways to accomplish this.

One common method is to use a PLL circuit.
etc...

Or did I miss understand that long tail?

I think you're describing a voltage-controlled oscillator.
See "http://en.wikipedia.org/wiki/Voltage-controlled_oscillator"
Read that and then come back.
