    An analytic method of digital interpolator optimization is proposed. Performance approaching or equaling that of full polyphase filter designs is achieved through the generation of orthogonal filters via singular value decomposition (SVD). This approach preserves the magnitude, group delay, and composite filter response and can eliminate the traditional restriction to ratio of integer interpolatio... View full abstract»

  • A high output impedance recording amplifier

    Publication Year: 1991, Page(s):897 - 904
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (348 KB)

    Since there is no treble lost from the amplifier to the head, less treble boost is required from the recording amplifier. Furthermore, because of the high-output impedance characteristic of the amplifier, a capacitor can be used to resonate with the head inductor to obtain treble boost. The result is a wide frequency response, a better signal to noise ratio (S/N), and less distortion View full abstract»
