Sinyalleri dijital olarak kodlanm\u0131\u015f oldu\u011fundan, sadece sinyal etkinli\u011fi de\u011fil, konu\u015fma ya da mesaj\u0131n i\u00e7eri\u011fini alg\u0131layabilir.

Devre \u015femas\u0131. Rar ar\u015fiv ekte verilmi\u015ftir. Iki ayr\u0131 dedekt\u00f6r birimleri vard\u0131r. Her dedekt\u00f6r \u00fcnitesi bir dipol anten, bir \u015fok ve bir diyot olu\u015fur. Anten al\u0131r GSM medyada sinyalleri. Daha sonra \u015farj k\u00fc\u00e7\u00fck bir miktar bobini ind\u00fcklenir. Diyot sinyal demod\u00fcle ve tespit tamamlan\u0131r. Diyotlar Schottky diyotlar veya germanyum diyotlar\u0131 olmal\u0131d\u0131r. Bir silisyum diyot ileri gerilim y\u00fcksek oldu\u011fundan, bu devrede yeterli bir sonu\u00e7 vermeyecektir.<\/em><\/strong><\/p>\n
