Digital signal receiver operating beyond the -3dB frequency
First Claim
1. A receiver for digital data for connection to a preceding signal path, said digital data having a lower to upper data frequency range, comprising:
- a received signal input terminal connected to a higher frequency gain circuit that has highest transfer amplitude at said upper data frequency within said lower to upper data frequency range where the signal has been attenuated in its higher frequency components in said preceding signal path and providing an amplified signal at an amplified signal output terminal and wherein the higher frequency gain circuit together with said attenuation in said preceding signal path has a slope in the transfer amplitude of +20 dB/decade at said upper data frequency; and
a latching circuit with two threshold levels, said latching circuit being connected with an input terminal to said amplified signal output terminal and an output terminal providing a digital output signal.

Abstract
A receiver for digital data connects to a preceding signal path and the digital data has a lower to upper data frequency range. The receiver includes a received signal input terminal connected to a higher frequency gain circuit that shows highest transfer amplitude at the upper data frequency within the lower to upper data frequency range where the signal has been attenuated in its higher frequency components in the preceding signal path and providing an amplified signal at an amplified signal output terminal. The receiver further includes a latching circuit with two threshold levels, the latching circuit is connected with an input terminal to the amplified signal output terminal and an output terminal providing a digital output signal.
