发明名称 GENERATION OF ANALOG SIGNAL BASED ON ONE-BIT SIGNAL
摘要 An analog signal generation apparatus includes: a converter which converts an input waveform signal into a one-bit signal; a control section which, in response to a mute-off instruction, controls a pulse width time length of the one-bit signal, output from the converter, to progressively increase from zero to a target value; and a filter which converts the one-bit signal, controlled by the control section, into an analog signal. The control section may further perform, in response to a mute-on instruction, control for progressively decreasing the pulse width time length of the one-bit signal, output from the converter, from a current value to zero. The mute-off instruction is given in response to turning-on of a power supply, and the mute-on instruction is given in response to a power supply OFF instruction.

主权项 1. An analog signal generation apparatus comprising: a converter configured to convert an input waveform signal into a one-bit signal; a control section configured to, in response to a mute-off instruction, control a pulse width time length of the one-bit signal, output from said converter, to progressively increase from zero to a target value; and a filter configured to convert the one-bit signal, controlled by said control section, into an analog signal.
