Frequency generator

sine↔square↔sawtooth↔triangle↔etc.

Generates sound with specified frequency and waveform type (sine, triangle etc.).

Note frequencies

basic tone↔1-st harmonic↔2-nd harmonic↔3-rd harmonic↔etc.

Table shows frequencies of music notes in twelve-tone equal tempered system (12-TET). Both basic tone and up to three harmonic frequencies are presented.

Periodic signals

sine↔triangle↔square↔mean value↔shape factor↔effective value↔etc.

Table shows properties of common periodic signals (sine, square, triangle etc.) such as absolute mean value, effective value or shape factor.
