Abstract

PURPOSE:To vary the gradient of period characteristics without generating waveform distortion, by providing a shifting means of moving the period characteristics in an optional direction in parallel. CONSTITUTION:When the output A of an inverter 7 is a power voltage +E, capacitors 8 and 10 are charged when it rises. Consequently, the output C of an amplifier 9 drops to a 0 level and the capacitor 10 is discharged through a constant current limiting circuit 11. When an output B drops down to a voltage E/2 supplied from a shifting means 14, the output C of the amplifier 9 is inverted to the voltage E and the output of the inverter drops to 0. Consequently, the residual charge of the capacitor 10 is discharged rapidly through the capacitor 8 and after the output V drops vertically, the capacitor 10 is charged up to the voltage E of the output c through the limiting circuit 11. When the output B reaches the E/2, the output C of the amplifier 9 is inverted to the 0 level and the output A comes to the voltage E.
