Acoustic signal processing apparatus
The Journal of the Acoustical Society of America, 1994An acoustic signal processing apparatus comprising infinite impulse response type digital filters and phase control device. The filters receive an acoustic signal. Outputs from the filters are synthesized to generate an output signal. The phase control device controls the phase of the output signals so as to cause limit cycle noise components generated

Laser-Acoustic Signal Processing
IEEE Transactions on Industrial Electronics and Control Instrumentation, 1969The variable delay and processing of RF and microwave signals is a current problem of considerable importance both for the many military applications in radar and electronic counter-measures and for the civilian applications in signal processing. The very low velocity of acoustic waves, as compared to the propagation velocity of electromagnetic signals,

Digitized acoustic radar signals
The Journal of the Acoustical Society of America, 1976To study the atmospheric structure, a data acquisition system for the monostatic acoustic radar was developed. It allows the direct comparison to in situ and other remote measurements. The data acquisition system consists of a transient recorder, an interface and a magnetic tape recorder. The transient recorder digitizes and stores the signal.
