  • 8 - Digital Circuits and Devices

  • Dennis L. Eggleston, Occidental College, Los Angeles
  • Book:
    Basic Electronics for Scientists and Engineers
    Print publication:
    20 November 2025, pp 221-266

  • Summary

    A variety of digital devices and circuits are introduced. The use of binary numbers in digital electronics is discussed. The AND, OR, XOR, NOT, NAND, NOR, XNOR, and buffer logic gates are presented, followed by a discussion of implementing logical functions. The Karnaugh map and Boolean algebra are introduced. Different ways of constructing logic gates are presented. Half- and full-adder circuits are developed. Several types of flip-flops are discussed. Building on this foundation, we introduce counters, decoders, shift registers, D/A and A/D converters, multiplexers, demultiplexers, memory arrays, automated processing, programmable logic devices, and digital EM communications.

  • 7 - Oscillators

  • Dennis L. Eggleston, Occidental College, Los Angeles
  • Book:
    Basic Electronics for Scientists and Engineers
    Print publication:
    20 November 2025, pp 192-220

  • Summary

    Oscillator circuits, categorized into relaxation and sinusoidal types, are introduced. Three examples of relaxation oscillators are given and analyzed: the SCR sawtooth, the transistor astable, and the 555 astable. Monostable operation of the 555 timer is also discussed. For sinusoidal oscillators, examples include a transistor RC, an op-amp Wien bridge, a Hartley, and a Pierce oscillator. Oscillator stability is discussed. Electromagnetic communications (AM and FM) are discussed as applications of oscillators.

  • 2 - AC Circuits

  • Dennis L. Eggleston, Occidental College, Los Angeles
  • Book:
    Basic Electronics for Scientists and Engineers
    Print publication:
    20 November 2025, pp 35-76

  • Summary

    Capacitors and inductors are introduced, along with their equivalent circuit laws. Switched RC circuits are thoroughly analyzed. The response of an RC circuit to a sinusoidal drive voltage is analyzed and leads to a discussion of high- and low-pass filters, phase shifters, integrators, and differentiators. The use of complex numbers in circuit analysis is introduced and applied to sinusoidally driven series RC, LR, and LRC circuits as well as the switched LRC circuit. Fourier analysis and its meaning are presented. The operation of transformers is introduced.
