Electronics Engineering Coaching: Section 5 Module 10

Microprogram – a set of instructions indicating primitive instruction

Handshake – solution to problem of connecting asynchronous devices

Gimmick capacitance – smallest capacitance formed when twisting two insulated wire

50 ohms – impedance of wire which is design to be used

Emitter current is heavily doped because it has to dissipate maximum power

Ondograph – an instruments which records the wave shape of voltage and current

Fermi-Dirac energy distribution function – is a distribution equation which explains the distribution of energies among different electrons within a crystal at a given temperature

Electron ballistics – measures trajectories

Advantage of CMOS family to TTL family – much reduced power

RC coupling – popular in low level audio amplifier due to its low cost

Abundance Ratio – ratio of number of atoms of one isotope

Permanent magnet – for direct measurement of DC voltage

Fuzzy logic – totally false to neutral to totally true

Pi network – can be two inductors, 1 capacitor or vise versa

Trickle charging – helps to keep a battery fresh, fully charged

Watt-hour Meter – an instrument that reads the electrical energy consumption of a consumer

Program counter – points to the next instruction
