Analog world
An old EETIMES Immortal works caption for Admiral Nelson at the Battle of Trafalgar said, "Where the hell am I going to find an analog engineer that doesn't smoke everything he builds?"

On a lighter vane (vein?), the whole world is an analog stage in which digital folks play bit parts.

I'm proud to be one of 'them there' analog types.  All problems are analog in nature.  Sometimes, with proper conditioning, we can find digital solutions.

Welcome aboard, Bill.

Importance of analog.
I agree 100% with Bill's article!

Try to use your cell phone without an antenna!

Antenna is just an LC analog filter!

Try to use your hybrid car without the power analog filter for your electric motor,

you will be at your garage the next day for a new electric motor.

Try to compare the speed of an analog multiplier with a digital one.

The first one works is on real time!

Try to run a microprocessor without an analog filter at the input of the signal.

Try to measure the EEG signal (10 microvolts) with a digital systems!

Analog is alive and will stay for a very long time.

The story of Linear device that was just bought by Texas is an eloquent description of the position of the analog in the electronic market.

Re: Hello Bill
Naysayers, deniers, whatever--that old analog reality will sneak up and bite them in the you-know-what, there's no avoiding it for most real designs,

Re: Hello Bill
Hello World! (and welcome to you Bill)

I have been involved in Analogue stuff since the early 70s - apart from a short 30 year stint in the IT world, I am back doing Analogue stuff - and loving it!

Even repairing old stuff has its joys - Designing new stuff is approaching heaven for me! And there's heaps of it to do...

Unfortunately, I am in a sea of naysayers (and youngsters) who just do not get the Analogue reality - but regardless, I soldier on. I look forward to ascerbic comments and being able to contribute where I can.

 

back to lurk mode!

My digits are stuck
We used to say there are only 2 digital problems, stuck at one and stuck at zero.  The rest are analog.

Re: Great to see you here Bill!
I'll poke around a bit and see if I can get Paul and Bonnie interested. It could happen.... And yes, I miss Pease. And Jim Williams. Well, we're standing on the shoulders of giants, so that'll improve the likelihood of success. I'll blog about that very soon.

Re: digital is just fast analog
Sorry, I can't go along with your approach and metaphor here. The particle/wave duality allows us to look at experiments and data from two legimate perspectives and live with apparent contradictions that puzzled physicists in the days before quantum physics as we now understand it. But "digital is a subset of analog" expresses a reality--they are not two equally legitimate ways of looking at signals, despite what the digital-first crowd would like us to think. One is a restricted version of the other, sort of how Newtonian physics is a "simplified" version of relativistic physics, and works--but only up to a point, under carefully defined circumstances.

Seems like this is a good subject for a post-conference discussion at a local waterhole, IMO!

Great to see you here Bill!
Great to see you here Bill - And big kudos on your opening volley. It's a nice take on an old colleague's maxim "all this silly digital stuff is just a special case of analog". Most of my engieering expereince has been with digital and embedded systems doing real-world tasks ranging from high-speed printers and early artificial vision systems to ultrasonic test equipment and have always been in awe of the guys and gals who were responsible for the analog/RF elements of my designs. Since there's a lot of analog actioon in the open-source hardware applications and some solid-state lighting projects I'm messing around with these days, it's great to find a place like this where we get the benfit of hanging with sarp analog minds.

 

looks like Brad's well on his way to building an all-star team of analog experts. I'm thrilled bout the present cast of characters already on this site and look forward to seeing who else he's got lurking in the wings. Maybe he can even convince Paul Rako or Bonnie Baker to pop in occasiaonaly. I just wish Bob Pease and Frank Goodenough were still around to add conversation...

Re: digital is just fast analog
If we are going to get all physics up in here, how about this: digital is particles, analog is waves, and the circuit board is the quantum world in which the signal exists as both. Might be stretching that metaphor a bit at this point though.

Re: digital is just fast analog
Cranky or not, doesn't matter to me--I'm just the messenger, reminding folks of the laws of physics here.
