Abstract: Delay times are modified in Ethernet network devices by adding an integer multiple of a delay interval to the minimum interpacket gap (IPG) interval, and decrementing the integer in each network station in response to detected activity on the media. Each station has a unique integer value from the range of zero to the number of stations (N) minus one. The unique integer value ensures that each station has a different delay interval in accessing the media after sensing deassertion of the receive carrier. The station having a zero integer value will have its integer counter reset to (N-1) after a station transmits a data packet on the network, and the stations having nonzero integer values decrement their respective integer counters. Each network station also includes a deferral timer that counts the maximum delay interval of (N-1) delay intervals plus the minimum IPG value, and thus establishes a bounded access latency for a half-duplex shared network.

Abstract translation: 通过将延迟间隔的整数倍添加到最小分组间隙（IPG）间隔，在以太网网络设备中修改延迟时间，并且响应于媒体上检测到的活动而递减每个网络站中的整数。 每个站具有从零到站数（N）减一的唯一整数值​​。 唯一的整数值确保每个站在感测到接收载波的取消消息之后在访问媒体时具有不同的延迟时间间隔。 在站点在网络上发送数据包之后，具有零整数值的站将其整数计数器重置为（N-1），并且具有非零整数值的站减少其相应的整数计数器。 每个网络站还包括延迟定时器，其计数（N-1）个延迟间隔的最大延迟间隔加上最小IPG值，从而建立半双工共享网络的有界访问等待时间。

Abstract: A system for detecting a mismatch between first and second input signals includes first and second analog-to-digital converters, a time-division multiplexing circuit, first and second processors, a time-division de-multiplexing circuit, and a gating circuit. The first processor includes a first sinc filter, a first trimmer, a first infinite impulse response (IIR) filter, and a first high pass filter (HPF). The second processor includes a second sinc filter, a second IIR filter, and a second HPF. A bandwidth of the second IIR filter and the second HPF is greater than a bandwidth of the first IIR filter and the first HPF. A transfer function of the first IIR filter and the first HPF uses floating-point coefficients and a transfer function of the second IIR filter and the second HPF uses coefficients that are an integral power of two.
