    The bandwidth of the idler circuit of a parametric amplifier is discussed, and reductions in bandwidth associated with stray reactances of the diode encapsulation and filter networks required to complete the idler circuit are described. A balanced idler circuit using two diodes is shown to approach the theoretically maximum idler bandwidth. A 3000 Mc/s amplifier is described having a 10% bandwidth... View full abstract»

  • Automatic high-speed measuring systems for complex products and shapes: interdependent computation and cybernetic inspection machinery

    Publication Year: 1964 , Page(s): 337 - 348
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (1956 KB)  

    A high-speed self-adaptive system of inspection is described and the reasons for evolving it are explained. Sequential measurement on a transfer-line is used to measure complex-shaped parts reliably to effective accuracies between ± 1 to 2 microns. Each measured dimension is stored up in analogue memory devices and later read-out as the object reaches the sorting or pass/reject gates. The decisio... View full abstract»

    The paper gives the analysis and d.c. design criteria with experimental results for high-speed current-switching circuits. Some improved forms of the basic current-switching circuits have been suggested. These modified circuits considerably ease the stringent tolerance requirements of the components and the power supplies of the original circuits in addition to reducing the number of components an...

  • Electronic melodic instruments

    Publication Year: 1964 , Page(s): 365 - 371
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (1153 KB)  

    An historical survey of electronic melodic instruments requiring a performer is given, together with an appraisal of their relationship to the art of music. It is argued that the most promising role for this class of instrument is in the spheres of amateur music and the teaching of music rather than as a successor to traditional instruments. The principles of design of a new instrument for the for... View full abstract»

  • Simulation by a single operational amplifier of thirdorder transfer functions having a pole at the origin

    The paper discusses a method for the simulation of third-order linear transfer functions, having a simple pole at the origin, with the aid of only one operational amplifier and a two-terminal network consisting entirely of resistors and capacitors. The design equations and conditions of physical realizability are given. Some of the salient advantages, disadvantages and limitations of this techniqu... View full abstract»

  • Noise in silicon carbide non-linear resistors

    Publication Year: 1964 , Page(s): 381 - 383
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (532 KB)  

    This paper deals with the noise arising in excess of thermal noise when a steady current is passed through a silicon-carbide nonlinear resistor. Curves are given showing the variation of excess noise with current for four different resistors. Pulses of an amplitude considerably greater than the r.m.s. value of the excess noise are found to occur. These are photographed and their amplitude is measu... View full abstract»

    The results of experiments carried out to show the effects of baking process on the noise in excess of thermal noise produced in carbon composition resistors are given. Resistors of 1/2 watt and 1 watt rating, having various nominal resistance values, were tested and curves are given showing the variation in noise with steady current. View full abstract»

  • Correlation techniques in studio testing

    Publication Year: 1964 , Page(s): 387 - 395
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (1137 KB)  

    Correlation techniques allow the separation of signals which have arrived by paths of different transit times or originated from different sources. This ability is of assistance in certain types of acoustic testing in studios or other enclosures. The construction of an analogue correlator to derive the correlation function between two signals is described. Its application both in laboratory and in... View full abstract»
