Claim 11:
12. The image signal transmission apparatus of claim 11, wherein a zero and two poles of a frequency response of the front-stage driving circuit are determined by a plurality of circuit parameters of the front-stage driving circuit, the circuit parameters comprise a resistance Rd of each of the two load resistors, a capacitance Cd of each of the two load capacitors, a resistance 2Rs of the adjusting resistor, and a capacitance Cs of the adjusting capacitor;
wherein a transconductance of the two input transistors is gm, the zero is 1/(RsCs), the two poles are respectively (1+gmRs)/(RsCs) and 1/(RdCd), a transfer function between the digital input signal and the front-stage output signal is (gmRd)(1+sRsCs)/(1+sRcCs+gmRs)(1+sRdCd)), and a direct current (DC) gain of the front-stage driving circuit is (gmRd)/(1+(gmRs)).
