Title:
DIGITAL SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JPH01143516
Kind Code:
A
Abstract:
PURPOSE:To set the analog signal characteristic to a desired state simply and quickly by scanning one variable axis at a prescribed speed, deciding the other according to an operation signal and controlling the device based on the two variables obtained in this way in the case of the operation of the frequency characteristic or the like. CONSTITUTION:A CPU 2 scans the frequency axis of a designated frequency band when a scan start key 7f is operated at the automatic mode and a cursor display 8c is moved from the start position to the end position. When a sound pressure level adjusting fadar 6a is operated during the movement, a signal processor 1 is controlled so that the sound pressure level of the frequency band shown in the display 8c changes in response to the operation of the fadar 6a and a part of a graphic display 8g corresponding to the display 8c is moved. In this case in the relative mode, the sound pressure level being the addition of the sound pressure level given by the fadar 6a to the preset frequency characteristic is set. In case of the absolute mode, the sound pressure level given by the fadar 6a is set independently of the preset frequency characteristic.
