发明名称 Digital detection filters for electronic article surveillance
摘要 Digital implementation of electronic article surveillance (EAS) detection filtering for pulsed EAS systems is provided. Embodiments include direct implementation as a quadrature matched filter bank, as an envelope detector, a correlation receiver, and as a discrete Fourier transform. Pre-detection nonlinear filtering is also provided for impulsive noise environments.
