I know. I wasn't even born, and it gives me chills, too. Their Finest

Same here. Some days during the summer there are airshows around the
south coast and I sometimes see a couple of the last remaining flying
Spits pass overhead on their way to do another display. For a brief
moment I'm transported back to 1940. I'm not an emotional guy, but
there is something very moving about the experience. Think I must have
been a Spit pilot in my previous life.
There's a wonderful RAF museum just north of London; you can get there
with a train ride and a long walk (or long wait for a bus). There's
the only Spit I've ever seen in the flesh, and it's more beautiful
than the pictures can express.

Can't recommend the food in the cafeteria, though. Pack a lunch.

Which isn't the case at all, because, well, look at it. All you have to
do is declare that everybody's credit card is covered, with an unlimited
balance. This will be even cheaper than printing notes 24/7 at BP&amp;E.
This will raise the money supply to infinity. Inflation will then make
each dollar worth zero goods. You would have to make accounting software
than handles higher forms of carinality than mere infinity to make this
system work. There would have to be a new line of computers to run this
software because it would have to handle more forms of numbers. Computers
these days work in fixed point (integer) and floating point values. These
more advanced computers would have to handle fixed point, floating point,
flying point, space traveling point, needle point and pointless numbers.

"On my first confrontation with the P-38, I was astonished to find an
American aircraft that could outrun, outclimb, and outdive our Zero
which we thought was the most superior fighter plane in the world. The
Lightning's great speed, its sensational high altitude performance,
and especially its ability to dive and climb much faster than the Zero
presented insuperable problems for our fliers. The P-38 pilots, flying
at great height, chose when and where they wanted to fight with
disastrous results for our own men. The P-38 boded ill for the future
and destroyed the morale of the Zero fighter Pilot."...Saburo Sakai,

Considering that I designed it ~1968 it's not too shabby. The
matching PFD is the MC4044.

The MC4024 core structure was also fabricated on MECL III and will do
~300MHz.

Other of my PLL designs are now made in the 12000 series.

As long as we're on the subject, have you ever posted a schematic of
the MC1648 or discussed the AGC mechanism it uses?

Tim.
No I haven't, but it looks like I should... the publicized schematic
seems to be with errors.

When I have some free time (I'm up to my ears in work right now), I'll
post a description of how it works.

Hi Ken,

It is also a cruel thing to do to an op-amp so it is not allowed in the
US.


Did some opamps form an association or other special interest group?
Which one is their elected leader? I'd vote for the uA709. In the
differential category for the uA733.

The 3080 transconductance amplifier is a great part, not a bad current
source, but with limited capability of about 1mA or so maximum current
(15mA requested) and 12V maximum voltage compliance (15mA * 2k = 30V
requested), so we're required to give up a simple IC-purchase approach
and "roll out own" with well over 60V total rail-rail supply voltage.

That gives you a physical model, but how do you connect the darn thing
to a SPICE simulation?

I do not think a real telephone line is going to be amenable to
simulation with a simple RLC. It's going to act like a transmission
line, with a characteristic impedance somewhere centered around 100 ohms
but varying widely from one to the next, a widely varying reflection
coefficient, a great deal of loss, also varying, and with a length that
can be anywhere from a few feet to a few miles. In addition you'll have
some bonus signals injected from neighboring lines, free of charge.

Aside from that it should be a snap to simulate.
