I spent a fair amount of after-hour time at BL Archives 1Q 2016 digging up material for Shannon's Centennial (access to the archive thanks to Ed Eckert and Charlie Bahr) Eventually helped create

On the premise that telecommunications engineering may be considered one of the most complex and highly technical industries, more than usually dependent upon engineering, the author considers the

H E R E are at the present time two types of crystal quartz plates in general use as circuit elements for frequency stabilization at radio frequencies, namely, the X-cut and F-cut.

The advantages of the selenium rectifier over other types of dry rectifier are a high permissible working temperature (85degC.), a high current density (180 mA/cm2.

Determining the grade of service of a telephone connecting network, as measured, for example, by the probability of blocking, continues to be a major outstanding problem of telephone traffic theory

The fact t h a t successive frames of a motion picture are often very nearly alike has led to the consideration of schemes which transmit, for each point of the picture, the difference between the

One of the problems encountered in t h e utilization of t h e millimeterwave b a n d s for r a d i o - r e l a y systems is a t t e n u a t i o n resulting from precipitation.

A standard result known as Chebychev's inequality asserts that any two non-decreasing functions of a real random variable have non-negative correlation.

Knockout tournaments are often used in sports (or experiments where- preferences are registered by comparisons instead of measurements) to determine the champion of an event.
