    A digital h.f. multipath propagation simulator is described which can be applied to communications receiver and modulation techniques evaluation and operator training. It can also be applied to a variety of applications in the high-frequency field where programmable and repeatable ionospheric conditions require simulation. Simultaneous communications paths are simulated, four of which exhibit inde... View full abstract»

    The repeatability of insertion loss of the most commonly used coaxial connector pairs was tested between 100 MHz and 12 GHz. The resolution of the measurements was better than 0.0001 dB. With carefully performed connections the repeatability expressed in standard deviation varied between 0.0002 and 0.002 dB. These values are some 2¿3 times smaller than those published by Bergfried and Fisher.1 Th... View full abstract»

    The results of a theoretical study of the application of mapping and spectral techniques to the design of digital circuits, with special emphasis on combinational circuits, are given. The method has the great advantage that the derivation of circuit tests is an integral part of the circuit synthesis procedure. Other advantages of the method are that very elegant designs are produced which are comp... View full abstract»
