    This part of the paper concerning p.c.m. video signals describes two series of subjective tests performed to examine picture impairments caused by unwanted components which may be introduced into system I {PAL, 625-line} video signals while they are encoded in p.c.m. form. The first series of testsexamined the subjective effects of digital transmission errors. Both random singal-digital errors and... View full abstract»

    This paper develops the use of principal component analysis as an aid to quality assurance. The sensitivity of the analysis to changes in the statistical characteristics of the measurements is examined. The analysis can reduce the number of time series that have to be monitored for quality assurance. The technique is to linearly combine groups of the measurements. This grouping of measurements exc... View full abstract»

    Work on small narrow resonance line-width ferrite spheres in waveguide leads to a need for theoretical quantitative understanding of the interaction between the ferrite and the waveguide fields. Analysis in the literature has previously relied on equivalent circuits with voltage and current, but belief that the concept of electromagnetic fields comes more naturally to waveguides led to the analysi...

  • Signal recovery from repetitive non-uniform sampling patterns

    This paper describes a technique for using amplitude samples which have been taken at non-uniform intervals of time. The method is essentially indirect as the non-uniform samples are first converted into uniform samples, the conversion being based upon the impulse response of a practical realizable filter. The problems encountered in the process are analysed, and a procedure for determining the op... View full abstract»

    The applicability of thick film technique has been investigated for frequencies above 1 GHz. By usinga special technique (direct metal foil screens) integrated microwave circuits for frequencies up to 10 GHz have been fabricated. The special requirements for microwave thick film circuits are discussed and the electrical and technological properties of three selected microwave circuits are reported... View full abstract»
