Hi Fi Audio Tape to Sun Workstation Transfer System for Digital Audio Data

This thesis describes a subsystem developed to provide for the transfer of digital audio signals from a SUN SPARCstation 10 workstation to a digital audio tape (DAT) and vice versa. The new system expands the audio recording/reproduction options available in the laboratory by integrating an analog tape deck and a digital tape deck with the SUN workstation. The desired connection enables working with a larger audio bandwidth to achieve better audio performance and resolution in comparison to the present workstation audio capabilities. Performance measurements of the audio signal-to-noise ratio have shown an improvement of about 45 dB in the audio reproduction capability and about 35 dB in the audio recording capability. Total harmonic distortion for the new system is below the limit of the measuring instrumentation (less than 0.1%).
