Abstract: Waveform generator (40) is capable of generating an arbitrary waveform in quadrature format. Each of the I and Q components of the waveform is generated by addressing data in a plurality of non-volatile storage blocks (e.g. A-F for the I component) and demultiplexing (via unit 44 for the I channel) the retrieved data into a sequence forming the component which can then be combined with the other component in the analogue domain to produce the desired waveform.

Abstract: A method, of monitoring a series of products, of the kind in which the presence of foreign bodies in the product being monitored is detected by the characteristic magnetic field phase difference each material exhibits, is characterised in that the signal generated by a satisfactory product having no foreign body it is used as the datum for judging whether the next subsequent product is free from a foreign body or not.

Abstract: A waveform generator for generating a smooth version of an original waveform which contains abrupt transitions, includes a phase accumulator incremented at successive sampling times to produce an output representative of the phase of the original waveform, a phase scaler arranged to convert the residual contents of the accumulator following a transition from phase to time, computing means responsive to the time to calculate a number of samples along a smooth transition, each offset by that time from the sampling times, and a sequencer to replace the otherwise abrupt transition with the sequence of samples from the computed smooth transition.

Abstract: A phase locked loop (10) comprising: a tuneable oscillator (12); a mixer-based phase sensitive detector (18) to receive input signals from the tuneable oscillator (12) and a reference signal (20); a cycle slip detector (26) to receive input signals from the tuneable oscillator (12) and the reference signal (20), the cycle slip detector (26) being configured to generate an output signal when two consecutive pulses are present in one of its input signals without an intervening pulse in the other of its input signals; coarse tune signal means (32, 34) to receive the output signal generated by the cycle slip detector; and adding means (24) for adding a signal output by the coarse signal means (32, 34) to a signal output by the phase sensitive detector (18) to control the frequency of the tuneable oscillator (12).
