Abstract
In a previous study [W. A. Struzinski, IEEE Trans. Acoust. Speech Signal Process. ASSP‐31, 651–656 (1983)], OR‐ing loss data were provided for a system composed of electrical integrators followed by an OR‐ing device and a display. This analysis was for static signals. In this paper, consideration is given to a sinusoidal frequency modulation signal. For this type of signal, we examine an alternative processor where this is no pre‐OR‐ing device. The performance of the alternative processor is evaluated and compared with the previously analyzed system. An experimental performance comparison of the two processors was also conducted on the NUSC Acoustic Display Research Facility. Based upon the results of the subject analysis, it is concluded that for a sinusoidal frequency modulation signal, there should be no electrical integration prior to OR‐ing.[Work supported by NAVSEA.]
