| 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 (Fig. 9), as an envelope detector (Fig. 10), a correlation receiver (Fig. 11), and as a discrete Fourier transform (Fig. 12). Pre-detection nonlinear filtering (Fig. 13) is also provided for impulsive noise environments.
