b.) Characteristics of different waveforms

Different Wave Form Characteristics: (Videos embedded below)

  • Sine
    • Sine waveforms are characterized by smooth, periodic oscillation, defined by amplitude, frequency, and phase, which determine its height, repetition rate, and starting point, respectively.
  • Square
    • Square waveforms are non-sinusoidal periodic waveforms that alternate between two voltage levels with sharp, almost instantaneous transitions, characterized by its constant amplitude and a 50% duty cycle.
  • Sawtooth
    • Sawtooth waveforms are characterized by their distinctive shape resembling the teeth of a saw. Sawtooth waveforms have linear ramps , sudden drops, and repetitive cycles.
  • Triangle
    • Triangle waveforms are characterized by a symmetrical, linear rise and fall in amplitude, resulting in a triangular shape when plotted against time, and they contain only odd harmonics with amplitudes that decrease rapidly with frequency.
