BANDWIDTH LINITATION SIGNAL SHAPING CIRCUIT IN NON-ADJUSTMENT DIGITAL TYPE

摘要

The signal shaping circuit eliminates the intersymbol interference and jitter by suppressing the high frequency components from the transmitted signal. The device comprises a control unit(21) for generating address and control signal to prohibit the counting error of the external clock; a lookup table(22) for generating the digital data for the sinusoidal input; a D/A converter(23) for generating analog and DC signal of a specific level by using the lookup table(22) output.
