| Summary: | Approved for public release; distribution unlimited. === This thesis presents the design and testing of a microcomputer
controlled data acquisition system for an acoustical
imaging system. Analog sinusoidal signals are processed
through a 256 channel analog multiplexer to high speed phase
and amplitude detection channels. Analog to digital
conversion is accomplished with a microcomputer peripheral module. Data storage then follows in a 64K byte peripheral
memory. Interface with a cassette tape recording system is
accomplished for data transferral. |
