Smith charts are just as obsolete as Ohms law..............

With some of the Russian-trained engineers whose work my wife has
to
correct, Ohm's Law, as well as electrical codes, are mere
"suggestions".

Phil, with some of the AMERICAN trained RF folks I've
worked with, the Smith Chart presentation on paper or on
the display screens of various RF instruments is an
indispensable tool for quickly observing both narrow- and
wideband behavior of RF structures.

Ohm's Law of Resistance is universally accepted in the radio
and electronics community worldwide...but there are some
huge exceptions with "foreign" concepts such as the Smith
Chart. Olde-tyme hammes haven't a clue on what the
wonderful chart tells them nor can they see the relationship
between complex quantities nor understand "normalization"
of impedance. Something involving algebra of three or more
quantities is apparently "rocket science" to them. shrug

I could do complex quantity calculations on my little
AMERICAN-made HP-25 and HP-67 pocket calculators
(made in HP's old plant in Oregon) and can still do them
on the Singapore-constructed HP 32S II (but designed by
HP) I have now.

It was made in Indonesia Sweetums. Get SOMETHING right at least onece
in awhile WILLYA?

shrug

Of course it is fabricated in Indonesia. That's molded into the
back of the HP 32S II case. :-)

WHERE it was put together shouldn't matter, or should it?

Do you think the internal ROM has "different" constants
loaded into it just because of the distance between Indonesia
and Singapore? And WHICH part of Indonesia are you
(apparently) rooting for? [Singapore is a city-state on the
SE tip of the Malaysian penninsula, not far from Kuala
Lumpur, easily located...but Indonesia is several islands
farther east and south] My HP 32 was assembled in
1987...perhaps you are going to argue that it gives "old"
answers? :-)

You got caught in simple entrapment. :-) The only
contest was WHICH PCTA extra would start shouting and
hollering about ERRORS! MISTAKES! EVIL! :-) You beat
the others which were bound to jump in and do the personal
criticism bit with overtones of "he isn't worthy of being IN
here with us 'superior' PCTA extras!." :-)

OK, big calculating guy expert, where was/is the HP
scientific calculator complex? [Phil Kane should know]
When did the first scientific pocket calculator appear?
What preceded it out of HP, the old HP? Was Kellie's
name on programs in the HP programmable calculator
program library?

Irrelevant, you say? Of course it is in here...just as your
"correction" of where an HP 32S calculator is put together.
But that doesn't stop you going on some Philly Snipe
Hunt in here, does it? :-)

One excellent upgrade that HP did after the 67/97 series
was to add in COMPLEX quantity handling. Two numbers,
the Real and Imaginary parts, can be handled as it one
(scalar) number for the four functions. For impedance/
admittance calculations that is very very handy. Of course
one has to know what the formulas ARE in order to use
them...and to have the measuring equipment to supply
those numbers for calculation. One doesn't need to go
to Russia to "learn" those formulas. :-)
