Patent DE-3062796-D1 (DE)
Title: Switching amplifier for driving a load through an alternating-current path
Inventor: DIETZ WOLFGANG FRIEDRICH WILHE
IPC: H04N3/16
Filed: 1980-02-05
Granted: 1983-05-26
Abstract: An amplifier includes first and second switches coupled at a junction to form a series circuit. The series circuit is serially coupled with an inductor across a source of energizing potential. A capacitor couples the junction between the switches to a load. The switches conduct alternately under the control of a duty cycle modulator. The duty cycle modulation tends to vary the amplitude of the two opposite-polarity portions of the signal appearing across the load. A clamp is coupled to the junction of the series switch circuit and the inductor. The clamp operates during a first of the two alternate switch conduction intervals to clamp the voltage across the inductor at a fixed value. Since a direct voltage cannot be established across an inductor, the voltage across the inductor during the second switch conduction interval is established by the clamp voltage and the duty cycle, and varies with duty cycle. The amplitude of the signal at the junction of the two switches varies with duty cycle variations in such a manner as to maintain the signal of one polarity across the load at a constant amplitude.

Abstract: PCT No. PCT/GB82/00321 Sec. 371 Date Jul. 11, 1983 Sec. 102(e) Date Jul. 11, 1983 PCT Filed Nov. 10, 1982 PCT Pub. No. WO83/01714 PCT Pub. Date May 11, 1983.An amplifier which is particularly suitable for low supply voltage operation and which is relatively insensitive to power supply voltage variations includes a signal amplifying stage (11) and a control stage (10). The signal amplifying stage (11) includes the output load (13), such as a loudspeaker, in series with a transistor (12) which is controlled by a current mirror circuit (14, 15, 16) in the control stage. The circuit acts by continuously comparing part of the voltage across the output load (13) with a very low reference voltage arising from the difference in the base-emitter voltages of two transistors (14, 15) operating at unequal collector current values. This causes voltage excursion peaks appearing at the junction of the output load (13) and the amplifying transistor (12) to be clamped to a voltage equal to or otherwise related to that at the opposite side of the output load (13).

Abstract: Additional information is transmitted, in conjunction with message signals which are transmitted over a data switching center belonging to a public switched network. The data switching center is connected to teleprinter subscriber stations and teletex subscriber stations which are capable of transmitting and receiving message signals in accordance with different transmission procedures. The transmission of message signals between the subscriber stations occurs over at least one signal converter connected to the data switching center. After an occupation of the signal converter proceeding from a teleprinter subscriber station, the corresponding digital information are deposited in a memory of the signal converter by the data switching center upon each attempt to establish a connection from the signal converter to a teletex subscriber station. Under certain conditions, together with the message signal transmitted by the teleprinter subscriber station and contained in the signal converter, the additional information are emitted from the memory to the teletex subscriber station after a successful completion of a connection between the signal converter and the teletex subscriber station.
