Claims
- 1. A method for amplifying and separating an input signal into first and second segments and providing a first output signal comprising said first segments and a second output signal comprising said second segments, the steps comprising:
- amplifying an input signal by a differential amplifier having first and second amplifying means;
- providing a clock signal synchronized to said input signal and having a first state in time-correspondence with said first segment to be separated and a second state in time-correspondence with said second segment to be separated; and
- directing an amplified output of said differential amplifier to a first output terminal pair if said clock signal is in said first state or to a second output terminal pair if said clock signal is in said second state.
- 2. A polarity switching apparatus comprising:
- a differential amplifier having first and second amplifying means, each having an input and an output;
- polarity switch means including first, second, third and fourth polarity switches, each switch having an input terminal, an output terminal, and a control terminal;
- means connecting said first amplifying means output to the input terminals of said first and second switches;
- means connecting said second amplifying means output to the input terminals of said third and fourth switches;
- a first control signal terminal connected in common to the control terminals of said first and fourth switches;
- a second control signal terminal connected in common to the control terminals of said second and third switches;
- means connecting the output terminals of said first and third switches in common; and
- means connecting the output terminals of said second and fourth switches in common.
