[Heath] Peak and peak to peak/RMS relationship

[Ken Bakhaus]

I would like to clarify the relationship between peak and peak to peak/RMS so no one miscalibrates something based on the relationship which was recently posted with a slight error. Peak = 1.414 times RMS and Peak to peak = 2.828 times RMS for a sine wave where 1.414 represents the square root of 2. The constant of pi is not involved in this relationship. The numbers are derived from a calculus integral of the wave form. The constant in the relationship will vary for wave forms other than a sine wave.
