This thesis discusses the design and evaluation of an instrument that can estimate the probability density distributions of bandlimited, aperiodic electrical phenomena. This estimator can obtain the probability density estimates of signals that are contained within the frequency range of 100 cps. to 20 kcs. However, the basic design logic...
Reliability, the probability that a system will not fail but will
perform correctly at least until some arbitrary time, is becoming
an increasingly important concept in electronic system design. This
probability is evaluated using probability density functions which are
obtained analytically by forming mathematical expressions describing the failure distributions of...
The demand for transistor circuitry to perform within more
exacting specifications has created the need for a method to accurateIy predict transistor circuit performance. A method utilizing an
electronic digital computer for the analysis of direct-coupled transistor
amplifiers is explained in this paper.
The dc bias levels and the mid-band...
This paper discussed the human electrocardiogram, the instrumentation
used to graphically record it, and the design and performance
of a specialized system for vector cardiography: the Vector Electrocardioscope
(VECS) System. The introduction reviews in considerable
detail the pertinent known physiology of the heart, especially the
electrophysiology responsible for the genesis...
This thesis discusses the design and evaluation of an instrument
that can detect known signals in noise. This detector uses
two integrators to sense a difference in the received signal between
half-cycles of the known signal.
The detector is useful for sensing signals in the approximate
frequency range of 100...
