Abstract A finite sequence of equidistant samples (a sample‐train) of a periodic signal can be identified with a point in a multidimensional space. Such a point depends on the signal, the sampling period, and the starting time of the sequence. If t

A short train of equidistant samples rarely suffices to compute a reasonable approximation to a continuous-time signal. Hence, there arises a need for signal reconstruction methods that exploit multiple trains of samples. If the starting times of the

One of the reasons which impede applications of ultrasonic beam deflection flowmeters is their calibration that usually needs to be performed across the whole range of measured flow rates. In this paper we have aimed to show that given the directivit

We present a sampling hardware that can be used as a demonstration system for the triggerless random interleaved sampling method. The hardware is capable of acquiring sample-trains of lengths 2, 3 and 4 with a programmable inter-sample distance. Each

Reconstruction of undersampled periodic signals of unknown period is an important signal processing operation. It is especially difficult operation when the sequences of samples are short and no information on the inter-sequence time distances is giv

A single short sequence of samples taken at sub-Nyquist rate rarely allows for periodic signal recovery. If there is more than one such sequence and time offsets between these sequences are given, the signal approximation is possible and is known as
