Venn Diagrams and Boolean Algebra

A Venn diagram may be used to represent the possible logical states of a combinational logic system, typically having up to 3 input variables. Venn diagrams with more than 3 input variables becoming increasingly difficult to draw, given that for N variables, there...

Permeability

Absolute Permeability (μ) is the ratio of magnetic flux density (B) to magnetic field strength (H). Hence, For a non magnetic material, the ratio of B/H is a constant. The permeability of a classical vacuum (an 'ideal' vacuum, neglecting quantum mechanical effects)...

Conductance

The reciprocal of resistance (R) is conductance (G), which is measured in siemans (S). Hence: Worked Example 1 Find the conductance of a conductor of resistance 27 Ω. Show / hide answer G = 1 / R = 1 / 27   = 0.037 S = 37 mS Worked Example 2 Find the...

Binary Numbering System

The binary or base-2 numbering system may be regarded as the 'natural' numbering system to use with digital computers, since the low or high logic levels used internally by digital circuits correspond directly with the 0 or 1 values of a binary number. In the binary...
