摘要： A dual port memory is updated at substantially the same data sampling rate as a clock frequency of the dual port memory. The dual port memory stores data relating to each different parameter value in a stream of data samples, and provides the stored data from an address in the memory corresponding to the received parameter value. An updating element updates stored data and provides the updated data to an input of the dual port memory for writing back into the address corresponding to the received parameter value. A first port of the dual port memory is utilised as the output of the dual port memory coupled to the input of the updating element on a first clock cycle of the dual port memory, and a second port of the dual port memory is normally utilised as the input of the dual port memory coupled to the output of the updating element on a second clock cycle, the next address being accessed via the first port on the second clock cycle. A comparator receives the parameter value on the first clock cycle of the dual port memory and a next received parameter value on a second clock cycle, and provides a match signal if the received parameter value and the next received parameter value are the same. The match signal is utilised to enable the first port of the dual port memory to be used as the input for the second clock cycle so that the data updated by the updating element on the first clock cycle is provided at the first port rather than the second port and is therefore correctly provided to the input of the updating element on the second clock cycle.

摘要： Digital samples corresponding to a pulsed input signal are provided from an ADC to a memory for storage and to a pulse extraction circuit. The pulse extraction circuit detects the leading and trailing edges of pulses in the input signal. The digital samples are stored in both a Current memory buffer and a Next memory buffer. When a pulse trailing edge is detected, the Current buffer is stopped from storing further samples, the Next buffer becomes the Current buffer and a new buffer becomes the Next buffer. Digital data samples are then provided from the (previous) Current buffer after it has stopped storing samples.

摘要： Attenuation of a pulsed signal traversing a cable is assessed by identifying a pulse in a signal received after traversing the cable and determining first and second reference signal levels in dependence upon characteristics of the pulse. A measurement is made of the slope of the pulse between the first and second reference signal levels (such as 25% and 75% of the peak pulse magnitude), and this measurement is used to determine an indication of the cable attenuation. The cable attenuation may in turn be used to determine a threshold for indicating loss of signal during a measurement operation.

摘要： The magnitude of a pulse in a signal having both positive and negative polarity pulses (for example, a ternary PDH signal) is determined by measuring the magnitude of multiple samples of the signal. A reference level for the signal is determined from a plurality of these sample magnitudes, and the magnitude of a pulse in the signal is determined from the sample magnitudes and the reference level.
