1.6 Conversion From Decimal Numeration
Because octal and hexadecimal numeration systems have bases that are multiples of binary (base 2), conversion back and...

1.5 Octal and Hexadecimal to Decimal Conversion
Although the prime intent of octal and hexadecimal numeration systems is for the “shorthand” representation of...
1.4 Octal and Hexadecimal Numeration
Because binary numeration requires so many bits to represent relatively small numbers compared to the economy of the...
1.3 Decimal versus Binary Numeration
Let’s count from zero to twenty using four different kinds of numeration systems: hash marks, Roman numerals,...
1.2 Systems of Numeration
The Romans devised a system that was a substantial improvement over hash marks, because it used a variety of symbols...
1.1 Numbers and Symbols
The expression of numerical quantities is something we tend to take for granted. This is both a good and a bad thing in...
13.12 Tubes versus Semiconductors
Devoting a whole chapter in a modern electronics text to the design and function of electron tubes may seem a bit...
13.11 Microwave Tubes
For extremely high-frequency applications (above 1 GHz), the interelectrode capacitances and transit-time delays of...
13.10 Display Tubes
In addition to performing tasks of amplification and switching, tubes can be designed to serve as display...
13.9 Ionization (gas-filled) Tubes
So far, we’ve explored tubes which are totally “evacuated” of all gas and vapor inside their glass envelopes,...
13.8 Tube Parameters
For bipolar junction transistors, the fundamental measure of amplification is the Beta ratio (β), defined as the ratio...
13.7 Combination Tubes
Similar in thought to the idea of the integrated circuit, tube designers tried integrating different tube functions...
13.6 The Pentode
Another strategy for addressing the problem of secondary electrons being attracted by the screen was the addition of a...
13.5 Beam Power Tubes
In the beam power tube, the basic four-element structure of the tetrode was maintained, but the grid and screen wires...
13.4 The Tetrode
As the name suggests, the tetrode tube contains four elements: cathode (with the implicit filament, or “heater”),...
