Communication system

A communication system comprising:

• a push-pull transmitter circuit including a high-side drive element and a low-side drive element to transmit communication signals having HIGH and LOW level binary values, the transmitter circuit also including a reflection signal attenuator circuit configured to attenuate an effect that reflection signals appearing on a transmission line of the communication system has on the communication signals by biasing the reflection signals outwards of an amplitude direction of the communication signals to prevent contamination thereof;
• and
• a receiver circuit configured to receive and discriminate HIGH and LOW levels of the communication signals with a binarization voltage threshold,
• the reflection signal attenuator circuit including:
• first and second rectifier elements connected in series to the high-side drive element and the low-side drive element, respectively, and configured to prevent the reflection signals from flowing back to a power supply side from the communication signals;
• and
• first and second voltage cap elements connected in parallel to the high-side drive element and the low-side drive element, respectively, and configured to add or subtract capping voltages, equal to approximately 1.5 to 3 times upper or lower boundaries for a HIGH level voltage of the communication signals, to or from the boundaries when passing the reflection signals from the communication signals therethrough.
