Abstract

An experimental investigation of a stationary random process will involve the measurement of the mean values and probability distribution of a random function of time. This thesis describes an automatic ten channel "statistical analyzer" for measuring the probability distribution function of a continuous or discontinuous function of time that can be represented by a suitable electric voltage. The "statistical analyzer" is based upon a system of pulse amplitude modulation, followed by pulse height selection and pulse counting. An equation is developed by means of which the mean values can be computed from the distribution function. Finally, sample applications from the field of turbulence research are given.
