can we convert electrical pluses in to computer machine language .. ?

The starting point would be to define the meaning of the pulses and to establish an interface circuit of some sort that the computer can access.

Don't suppose you remember the days when 'home computers' used compact cassette tapes for program storage?

Umm, that's what computers do...and I group everything which has a processor in with that.

We can't talk in electrical pulses, but we can type. Keyboards convert what we type into electrical pulses. The code (ASCII) is converted to a format which displays on the monitor. That's just feedback because we catn tpye do good all of the tim e.

If you wan't to talk to your computer, you need voice recognition of some type. That's more direct, but it's converted to electrical pulses right away.

A popular poster on this site has a tage line: "There are 10 types of people in this world, those who understand binary and those who don't"...something like that.

Fiber optic is a much better method. The frequency spectrum/bandwidth on multi-mode fiber is astounding. Wire is more limited (electrical pulses, per se). "Light" computers are on the horizon for the average consumer. Then we are off to the races.

Get it?

Computers use binary code already. Series of ones and zeros. These can easily be created by a series of "pulses". Say you have an analog signal of pulses, like a fully rectified sine wave. Now say you clock a bit every .5 seconds. Anytime the clock is triggered, if the value of the sine wave input (at that very moment) is above a certain threshold value (say five volts) a 1 bit will be entered, and if it is below that threshold a 0 will be entered. Next would be writing a code to take every set of 8, 10, 16, etc. bits and converting it into whatever program you are talking about...

hello,

you can easily convert the electrical signal/pulses in to the computer language by selecting some threshold value which will depends upon on and compare it with signal/pulses, so if signal/pulses value is greater than the threshold value assign high(i.e. 1) and if signal/pulses value is less than the threshold value assign low(i.e. 0) so that your whole signal/pulses is converted into sequences of zero's and one's which is binary language and easily understand able by computer.

Computers use amplitude modulation

If you use frequency modulation to compile a machine language you are then bound by that code. You would all so be slowing down the rate of transfer. Circuits may need more then one wave to pass to detect change in frequency. As the technology changed for faster component switching rates. It could not utilize the advantage with out changing the code as you would be bound by the frequency it was written in. It would also increasing the size of circuitry. Switching circuit is much smaller and simpler then that which would be needed in detecting changes in frequency.
