    The use of uniformly distributed capacitance-resistance lines as cross-coupling circuits for transistor multivibrators is considered. The differential equation which governs the voltage across the line at any point is set up; this equation is the one-dimensional heat conduction equation. Boundary conditions are derived corresponding to the different parts of the multivibrator cycle. A numerical me... View full abstract»

    This note develops the concepts of characteristic impedance and propagation constant using matrix methods. It shows that they can be interpreted in terms of the eigen roots and vectors of the transfer and impedance matrices. It is not suggested that the methods are quicker than the normal ones, but that this approach provides an alternative interpretation of the filter parameters. View full abstract»

  • The analysis and demonstration of a method of generating v.l.f. noise

    Publication Year: 1965, Page(s):46 - 52

    The paper describes the analysis of a method of generating v.l.f. white noise based on the sampling principle. A wide-band source of noise is used and a narrow band at fairly high frequency over which the power spectrum is flat is extracted using a band-pass filter. The power spectral densities that result from sampling this band for different sampling frequencies are derived. The case of practica... View full abstract»

  • Z-transforms and their applications in control engineering

    Publication Year: 1965, Page(s):53 - 67

    The paper describes the z-transform theory and its application. The background theory is built up in four stages from the continuous convolution integral, through the real-time impulse theory, to the z-transform. It is stressed that, unlike the Laplace transform, the z-transform is only an approximation. Engineering units are used throughout and emphasis is given to the correct representation of t...
