摘要:

ABSTRACTA method is described for measuring capacitance at HF and VHF using coaxial cables. The equipment required for this method is normally available even in a moderately equipped electronics laboratory. The method is of wide applicability but is particularly suited to the study of capacitance of reverse biased semiconductor diodes. It is simple and accurate and needs very small r.f. voltages. Results of measurements using this method on same reverse biased diodes are also described.

摘要:

ABSTRACTMeasurements of E-plane radiation patterns of flanged H-plane sectoral horns are given. Apart from the two unkown parameters, viz. the flange length and the included angle, a third factor‘the position of the flange’is proved to have a very significant role in controlling the E-plane patterns of the H-plane horns. Broadening and narrowing of the beam are possible by a single flange of fixed angle, by adjusting its position from the open end. The essential conditions for these are derived theoretically and experimentally varified for four horns of different parameters. Measurements are given for a number of flanges in each case and for comparison, patterns are plotted when each flange is kept at the aperture and at the newly suggested positions.

摘要:

ABSTRACTA realization technique is presented for the synthesis of linear system transfer functions of any order having poles and zeros anywhere in the s-plane except the positive real axis, although the positive real axis can be approached to any degree of closeness desired. The transfer function is realized by means of grounded four-terminal RG networks constrained with a single operational amplifier. The realizations are transformerless.

摘要:

ABSTRACTThe techniques of manufacturing precision metal film resistors, using two different types of process are given. The first utilizes the vacuum deposition of nickel chromium alloys on ceramic substrates, using an electron bombardment evaporation source; and the second an electroless type plating of nickel and cobalt compounds. The electrical characteristics and test performances are reviewed.
