Title:
変化するデータ転送速度の通信チャネルのためのフィルタ制御
Document Type and Number:
Japanese Patent JP2005522135
Kind Code:
A
Abstract:
Processing circuitry includes an analog filter and filter control circuitry and processes an analog signal having a varying data rate. The analog filter filters the analog signal based on a transfer characteristic to transfer a filtered signal. The filter control circuit processes a data clock signal corresponding to the varying data rate and a reference clock signal to generate a filter control signal to adjust the transfer characteristic in proportion to the varying data rate. The analog filter adjusts the transfer characteristic in proportion to the varying data rate in response to the filter control signal. The processing circuitry may be implemented in a tape, magnetic, or optical drive.
