Disclosed herein are a passive equalizer and a high-speed digital signal transmission system, including first and second impedances connected in series to a first transfer line, third and fourth impedances connected in series to a second transfer line, a first inductor connected in parallel between the first impedance and the second impedance, a second inductor connected in parallel between the third impedance and the fourth impedance, and a resistor connected in series between the first inductor and the second inductor.

Passive equalizer and high-speed digital signal transmission system using the same

Disclosed is a multilayer printed circuit board. The multilayer printed circuit board includes a power source surface to provide power to each component disposed on the power source surface, a ground surface having a reference voltage, a strip line which passes through the power source surface and/or the ground surface so as to transmit signals between components, an antenna installed in proximity to a sectional region of the power source surface and the ground surface, and an electromagnetic wave reduction member which is provided between the power source surface and the ground surface to effectively reduce an electromagnetic wave generated from the strip line.

Multilayer printed circuit board having electromagnetic wave reduction member

A radio receiving apparatus deterioration of a receiving sensitivity of an antenna used in the radio receiving apparatus due to noise generated from a circuit board disposed within the radio receiving apparatus. The radio receiving apparatus includes a body, a printed circuit board provided within the body, an antenna provided at an area outside of the body and adapted to receive an external signal, and a noise attenuation member provided at the printed circuit board and adapted to attenuate noise generated from the printed circuit board, to prevent deterioration in the receiving sensitivity of the antenna.
