By utilizing this four-conductor star-quad configuration, the cable design provides enhanced rejection of noise and interference, resulting in cleaner and more accurate signal transmission. This makes star-quad cables particularly useful in environments where electromagnetic and radio frequency interference i...
An A/D and D/A converting circuit, a digital coding/decoding circuit and a digital modulating/demodulating circuit are embedded in a conference discussion unit and a system host of the digital conference discussion device respectively so as to convert analog signals into digital signals which are...
