信号输出电路
摘要：
信号输出电路(3，51，62，74，82)通过对输出晶体管(T1，T71，T72，T81～T86)的驱动进行控制，从上述输出晶体管的主端子输出梯形波输出信号。上述信号输出电路具备对上述输出晶体管进行恒流驱动的驱动部(4，75，76，83～88)、和将上述驱动部的驱动能力周期性地变更的驱动能力变更部(5，64，77，89)。
摘要（英）：

This signal output circuit (3, 51, 62, 74, 82) controls the driving of an output transistor (T1, T71, T72, T81 through T86) to output a trapezoidal-wave output signal from a main terminal of the output transistor. The signal output circuit is provided with a drive part (4, 75, 76, 83 through 88) for driving the output transistor with a constant current and a driving capability changing part (5, 64, 77, 89) for periodically changing the driving capability of the drive part.
