ABSTRACT:
A high frequency oscillator and a low frequency oscillator are provided to produce a high frequency cutting signal and a low frequency signal respectively. The high frequency cutting signal is modulated by a signal produced by differentiating the low frequency signal to form a coagulation signal. The high frequency cutting signal and the coagulation signal are compounded on a time division basis by a blend control signal generated by a blend control signal generating circuit to form a blend signal.
