Abstract

PURPOSE:To reduce the ambiguous working region of the limiter by comparing the absolute value of the limiter output of the data input signal with the threshold level and then giving the control to the limiter output value with the logic output of the multispot sampling of the comparison output. CONSTITUTION:The positive and negative limiter output levels are supplied to added 1 via NAND gates 16 and 17 or NAND gates 15 and 17 and in accordance with the plus or minus of the code which is detected out of data input signal IN to be then compared with the output of threshold level storing register 18. This comparison output is sent to shift register 19, and the logic sum output of the multispot sampling is obtained to be supplied to AND gate 21 and in order to give the control to the limiter output level. As a result, the amplitude detection is assured in case the level of the signal frequency is approximate to the threshold level, thus reducing the ambiguous working region of the limiter.
