Abstract

459,422. Valve circuits. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. March 27, 1936, No. 9141. Convention date, March 29, 1935. [Class 40 (v)] It is found that when a saw-tooth oscillation is amplified, a distortion of the kind shown in Fig. 2 occurs, the portion 10 of the wave form degenerating into a curve 11. According to the invention, this is overcome by connecting in the grid or output circuits of the amplifier a filter which passes high frequencies better than low frequencies. This circuit preferably comprises either a condenser 10 in parallel with a resistance 11, or a resistance 12 in series with a choke 13. Typical values of the components are given in the Specification.
