<p>PURPOSE:To obtain a simply constituted and easily-adjusted unit by controlling the gain of an amplifier by a linearizing output signal that a read only memory generates corresponding to the output of an A-D converter. CONSTITUTION:Analog input signal ei is A/D-converted 2 and a constant for linearization according to the ouput signal of it is read out from read only memory unit 3. By the read-out constant, the gain of gain control amplifier 4 is controlled by controlling the gain of the gain control amplifier 4, thereby obtaining output eo equivalent to linearized input signal ei.</p> |
