This thesis is concerned with the design of an external
multiplication package which can be utilized as an I/O device
with a PDP-8/L computer. The multiplier and multiplicand are
assumed to be 12 bit integers. The 24 bit product can be
transferred back to the accumulator of computer 12 bits...
In recent years, studies indicate that the second formant
of normal speech contains the majority of the information necessary
for speech intelligibility. This thesis presents a system to
translate the second formant frequencies to within a more adequate
hearing range of the partially deaf.
The digital speech translator, DISTRAN, utilizes...
This thesis is concerned with the logic design of a
small digital computer employing Read Only Memory(ROM) in
a special type of arithmetic unit(AU). The AU is controlled
by the ROM and is capable of performing a large number of
operations. The performance of the unit with its associated
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
The suitability of discrete least-squares optimal (Wiener) filters
for deconvolution of tone-burst waveforms is studied. It is shown
that: (1) such waveforms are not well suited to these filters without
preprocessing, (2) the use of exponential weighting results in a significant
improvement in filter performance and (3) that "phase-unwrapping"
As a result of the automation revolution, robots
are assuming ever more complex and demanding tasks.
Robot system control schemes for fast and precise robot
motion require utilization of the entirety of the robot
dynamic formulations and the ability to evaluate these
formulations in real-time. The dynamic formulations,
This paper discusses the design strategies for interface of bus
architectures. It also describes the design of interface between the
two popular bus architectures, the Micro Channel and the Nu Bus.
The main objective of this thesis is to develop a procedure for
bus interface design and use this procedure...
