    摘要： This disclosure describes techniques to sample electrical data streams in coherent receivers. For instance, an analog-to-digital converter (ADC) samples the received electrical data stream at a sampling rate that is nominally twice or greater than twice the symbol rate of the electrical data stream that the ADC receives. A digital filter receives the digital data stream from the ADC, and digitally filters the digital data streams to output a filtered digital electrical data stream at an effective sampling rate that is less than the sampling rate and less than twice the symbol rate, and greater than or equal to the symbol rate.

    摘要： This disclosure describes techniques to utilize pluggable photonics module in high data rates optical communications systems such as some coherent optical communications system. The pluggable photonics module plugs into a host board. The host board includes a processor that compensates for distortion caused by data streams traveling across the pluggable interfaces that the pluggable photonics module and host board use to couple to one another.

    摘要： A golf ranging system is provided where a golfer positions a ranging unit at a ball position, indicates which hole is being played and the ranging unit reports the distance to the pin for that hole and/or the distance from the tee for that hole. The ranging signal is a direct sequence spread-spectrum signal and the ranging is repeated many times and an average taken, to improve the accuracy of the distance measurement. Optionally, the ranging system could operate over multiple frequencies to avoid interference. The multiple frequencies are scanned until an interference-free channel is found, or measurements are made at several frequencies and averaged. The pin unit might be housed just beyond the pin and include an offset to the pin. The offset can be set by simply sending an offset signal from a standard ranging unit, or a specially configured course management unit, held at the pin or manually entered via a serial port.
