What is a Square-Wave

  A square wave is a non-sinusoidal periodic waveform (which can be represented as an infinite summation of sinusoidal waves), in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration spent at minimum and maximum.   The transition between minimum to maximum is instantaneous for an … Continue reading What is a Square-Wave

What is a Sine Wave

  The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation. It is named after the function sine, of which it is the graph. The sine wave occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields.   The sine wave is … Continue reading What is a Sine Wave
