<p>PURPOSE:To reduce the number of circuits and to lighten the burden by processing a means which outputs frequency information of a step waveform and amplitude information and a control means with one microprocessor for plural signals of a continuous signal and an intermittent signal. CONSTITUTION:When a control section 1A receives a command of outputting a control signal from a host control device, the control section 1A outputs a pattern of a VTR control signal to a frame control section 1C depending on a kind of an output signal. An element output section 1B is operated with a prescribed timing, by using this pattern, a frame control 5E selects the output of a rectangular wave outputted from an element output section 5D with a frame unit when it is ON state and selects no output when it is OFF state. Thus, a construction level inputted at a edge of the rectangular wave is latched and a step wave is generated. Thereby, a means 1 which outputs frequency information of a step waveform and amplitude information and a control means can be processed with one microprocessor for plural signals of a continuous signal and an intermittent signal. Therefore, the number of circuits can be reduced and the load of the host control device can be lightened.</p> |
