    One proposed method of reducing the channel capacity requirements for the transmissionof television signals over long distances is known as frame difference signal (f.d.s.) coding. This method implies the recoding of television signals so that only those parts of every frame are transmitted which are different in two consecutive frames. In order to assess the possible savings in channel capacity r... View full abstract»

  • A computer program for analysing networks containing three-terminal active devices characterized by their two-port parameters

    The paper describes a general-purpose computer program which may be used to calculate the performance of a wide variety of 2-port networks. The circuit to be analysed may contain 3-terminal active devices (such as transistors) provided their 2-port parameters are known, and there are no restrictions (apart from an upper limit to the size of the circuit) on the manner in which the resistors, capaci...

    The characteristics of anode structures suitable for coldcathode high-power magnetrons have been investigated analytically and experimentally, with special emphasis on increasing the interaction and maximizing the area of coherent interaction with the electron beam at a given frequency. The structures analysed were designed for large mode separation, high interaction impedance, and easy coupling t... View full abstract»

  • Optimum line and crossed arrays for the detection of a signal on a noise background

    Publication Year: 1965 , Page(s): 101 - 112

    The paper relates to the design of hydrophone or antena arrays together with the associated signal processing networks. For the detection of weak signals in a noise background the outputs from the individual receivers may be combined by means of linear amplifiers and time delays. For a signal of known time dependence and spatial form there is an optimum set of processing networks which maximizes t... View full abstract»

  • The possibility of an interaction anomaly in acoustic receiving arrays and radio arrays

    Publication Year: 1965 , Page(s): 113 - 116
    Save to Project icon | Click to expandAbstract | PDF file iconPDF (426 KB)  

    The conditions whereby interaction anomalies which occur in transmitting arrays could arise in acoustic or radio receiving arrays are established. It is concluded that the effect will only occur in special cases: for close packed resonant acoustic arrays and for radio arrays with thick dipoles arrayed asymmetrically. View full abstract»

    This paper treats the antenna as an information processing device. By representing the antenna as a spatial (as well as temporal) frequency filter, information theory concepts can be applied so as to maximize the information content or rate at the system output or to minimize the information content in the system error. Rather than attempt to satisfy classical antenna design criteria such as maxim... View full abstract»

  • Coupled-wave description of the absorption-type ferrite modulator

    Coupled wave theory is applied to the absorption type ferrite modulator. The importance of the quantities (¿x¿ ¿y)/K and (ßx¿ßyK) in determining the attenuation of the incident polarization are thereby demonstrated. For maximum attenuation we require (¿z¿¿y)/K= ¿2 and (ßz¿ ßy)/K = 0. Some experimental data confirming the effect of the quantity (¿x¿ ¿y)/K on the loss of the incident... View full abstract»
