Master Industrial Electronics N4: The Ultimate Guide to PDF Notes and Exam Success Binary: Base 2 (0, 1)

: Covers transformer types (step-up, step-down, center-tap), transformer ratios, and rectification (half-wave and full-wave bridge rectifiers). Amplifiers (15%)

Number Systems:

  • Binary: Base 2 (0, 1).
  • Decimal: Base 10.
  • Hexadecimal: Base 16 (used in PLC programming).
  • BCD (Binary Coded Decimal): Representing decimal digits using 4-bit binary nibbles.

Unlike previous levels that focus heavily on resistors, capacitors, and inductors, N4 introduces the student to the "brains" of modern machinery. The subject is theory-heavy but requires a deep understanding of practical applications. Key topics covered in standard N4 notes include:

  • Bipolar Junction Transistors (BJT): NPN, PNP
  • Biasing circuits (voltage divider, fixed bias)
  • Load line and Q-point
  • Transistor as a switch and amplifier
  • Field Effect Transistors (FET) – basic introduction
