World’s first fully digital radio transmitter built purely from microprocessor technology

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless communications capabilities of everything from 5G mobile technology to the multitude devices aimed at supporting the Internet of Things (IoT).

The significance of this new technology cannot be overstated: Every aspect of radio frequency generation is said to be created using a string of digital bits, and nothing else. There are no analog circuits, no filters, no chokes, none of the traditional circuitry and components expected in a radio transmitter. Consisting of a mere handful of components, including a couple of integrated circuits, an antenna, and not much else, the transmitter – dubbed Pizzicato – promises to change the face of wireless transmission.

Kind like an Arduino, but without any of the fancy bits?

>an antenna

I hope that interface with the aether is fucken digital too, don’t want any analogue coupling’n antiquated impedance transformations.

Not being a tech person, I find it difficult to understand this. I know of “antenna on a chip” antennas and that with spiral structure they can cope with a wide range of frequencies. This however seems to be talking about something quite different. The article describes two totally different and incompatible technologies.

1. Low frequency (below 1 GHz) dynamic switching capabilities to sense the radio environment and switch various settings as required, in real time.

2. High frequency (above 10 GHz) narrow bandwidth impossible using analog methods.

It’s not at all clear whether the new device has either of these. So, which or neither?

from reading the article it can possibly do both. because it is digital only it has a much tighter control over the frequency/ies it can broadcast on. it can also switch faster between them.

don’t mind me was having some fun
you know where the signal couples the aether
‘n’ travels the aether when all is done
our friend mr sinusoid he does he gets it there

That’s the problem with digital communication. “mr sinusoid” carries no data. He has to be damaged by transients in order to carry anything. I prefer mr sinc (not to be confused with mr sink) as a communication carrying pulse of minimum duration.

looks fine to me.

>That’s the problem with digital communication. “mr sinusoid” carries no data

yes was just toying with the ‘everything is digital’
how coupling to the aether requires mr sinusoid
nothin’ more’n nothin’ less, dear, truly so was all
so go you know little ol’ do like to have last word

must have been hard communicating with spark gap transmitters.

all you need is a rise and fall to produce the oscillations in the antenna. sinusoid isn’t necessary.

>must have been hard communicating with spark gap transmitters.

does it ‘rings’ in a resonant circuit
plenty harmonics’n splatterin’ shit

i am aware of the problems. just pointing out that a sinusoidal waveform isn’t necessary to transmit a signal.

>i am aware of the problems. just pointing out that a sinusoidal waveform isn’t necessary to transmit a signal.

well technically no, you can accelerate a charge and it produces EMR, still mr sinusoid features big coupling to the aether.

Point was space has a characteristic impedance, or equivalent characteristic impedance, is how it is understood here. So as seen from a radio device coupling into it…..

what?
