Abstract

PURPOSE: To increase a modulation rate by nearly equalizing at any time the non- conduction time when upper and lower pulse amplifiers are both OFF.
CONSTITUTION: When triangular wave a' whose duty cycle is set to any value than 50% is applied to one-side input terminals of upper and lower comparators 5 and 5', it is compared with positive potential (b) by comparator 5 to output a positive output pulse of waveform (d) and compared with negative potential (c) by comparator 5' to output a negative output pulse of waveform (e). Both outputs are applied to pulse amplifiers 6 and 6', so that a pulse waveform outputted from mixer 7 lastly will have non-conduction periods T1 and T2 nearly equal each other as shown by (f). As a result, the non-conduction time when an acoustic signal is applied to the signal input can be shortened to its minimum, so that its modulation rate can be increased.
