Abstract
PURPOSE:To generate simply pulses having many kinds of amplitude, period and pulse width, by constituting a circuit by plural pairs of voltage dividing circuits, plural timing generating circuits, and switch circuits which select outputs of both circuits to connect them to a pulse output circuit. CONSTITUTION:A circuit is constituted by three sets of voltage dividing circuits 1-6, 7-12, and 13-18 which generate upper and lower signals to determine a pulse amplitude value, timing generating circuits 19-24 which determine the period and a pulse width, and switch circuits 25-27 which select circuit outputs of these circuits to operate while interlocking with them. Now, when voltage dividing circuits 13-15 and 16-18 and timing circuits 23-24 are selected and an H level is applied to the base of transistor Tr28 of a pulse output circuit, the current dependent upon only Tr32 is flowed to resistance 33, and the potential at output point 47 is determined. When an L level is applied to the base of Tr28, currents of Tr30 and Tr32 are flowed to resistance 33, and the potential at output point 47 is lowered. This potential is determined by the set value of voltage dividing circuits, and the period and the pulse width can be changed by timing circuits, so that many kinds of pulse can be generated simply.
