13, ABSTRACT:, The invention relates to an amplifier comprising means for eliminating direct-voltage transients on the amplifier output. For this purpose there is provided a controllable voltage source, which is coupled to the output or to a point in the amplifier in such a way that the output voltage gradually increases to the steady-state value. The magnitude of the output voltage of said source which conducts current in one direction only can be con-, trolled by means of a control voltage which is continuously variable during the turn-on period and which is applied to its input. The voltage source is connected to the amplifier in such a way that, as the amplifier output voltage rises, it …

Why it's free to use
- Granted April 30, 1985. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended April 30, 2002.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
