Title: Improvements in or relating to amplifier baseline stabilization
IPC: G06G7/12
Filed: 1965-03-09
Abstract: 1,102,451. Recording and playback systems. AMPEX CORPORATION. 9 March, 1965 [16 April, 1964], No. 9909/65. Heading G5R. [Also in Division H3] In a recording system in which a magnetic head carries both " write " and " read " windings, asymmetrical signals applied to the " write " winding are inductively coupled into the " read " winding and produce a shift in the base-line of the read amplifier due to a net charge on the capacitances in this amplifier. In order to prevent this, the " write " winding 14, Fig. 3, is shunted by a series circuit comprising capacifor C 1  and resistor R 7 . Any asymmetrical inputs applied to this parallel combination induce a heavily damped symmetrical oscillatory signal into read winding which minimizes any charge on the capacitance in the read amplifier. The arrangement may be applied to a returnto-bias system as shown, or a return-to-zero system, Fig. 5 (not shown).

IPC: H04B10/2507
Filed: 1995-01-10
Abstract: PURPOSE: To eliminate the influence of crosstalk upon an optical signal from another normal light signal at the time of switching a light source to a stand-by light source by inserting a band-pass filter capable of passing only the wavelength of a stand-by light source in its steady state into an optical path for guiding a light signal from the stand-by source to a transmitting optical fiber. CONSTITUTION: Band-pass filters(BPFs) 14-1, 14-2 are respectively inserted between stand-by light sources 13-1, 13-2 and a multiplexer 11. The passing wavelength of these BPFs 14-1, 14-2 coincides with the wavelength of the light sources 13-1, 13-2 in their steady state. It is supposed that a light source 10-2 fails and an optical signal 2-1 is interrupted. In this state, the stand-by light source 13-2 is driven in order to generate a new optical signal 1-2. The wavelength of the signal 1-2 is almost equal to that of the light source 10-2. The temperature of the light source 13-2 is not stabilized and the wavelength may be varied during a period from the start of the light source 13-2 up to a steady state.  However only an optical signal transmitted through the BPF 14-2 appears on a wavelength multiplex signal 2 outputted from the multiplexer 11 because of the existence of the BPF 14-2, so that the influence of the temperature instability or wavelength variation of the light source 13-2 is not exerted upon the signal 2.
