Title: Unipolar/bipolar converting system
Inventor: KUSAMA TAKEO
IPC: H03M5/16
Filed: 1992-02-04
Abstract: PURPOSE:To always obtain a fixed and stable output impedance with simple configuration by separating unipolar pulse sequences into positive side and negative side pulse sequences and generating bipolar pulses by the respective separated pulse sequences. CONSTITUTION:A unipolar pulse input is frequency divided by a binary counter 1. The positive side frequency divided output is inputted to an AND gate 2, and the negative side output is inputted to a NAND gate 3. Resistors R2 and R4 divide a power supply voltage and compose of a voltage source. When there is the pulse output at the AND gate 2, a current flows through a resistor R1, and a diode 4 to the voltage source and the voltage is increased. When there is the pulse output at the NAND gate 3, the current flows from the voltage source through a resistor R3 and a diode 5 to the NAND gate 3 and the voltage is lowered. Thus, a bipolar output can be obtained as the voltage of the voltage source. The bipolar pulse is amplified at a prescribed amplification factor by an amplifier 6 and transmitted to a transmission line after matching the impedance through a resistor R6.
