Bog'liq 12-MA\'RUZA7-rasm. Qabul qilgich atrofidagi shovqin zonasida qurilmalarning joylashishiga misol:
bu yerda x uzatuvchidan T0 signalining tarqalishi radiusiga mos keladi. Xuddi shunday pck (qabul qiluvchining qamrovida ck) qabul qiluvchining qamrov zonasida uzatgichni o’z ichiga olishi ehtimoli quyidagicha hisoblanadi:
(6)
Formulalardan (5) va (6) α va β mos ravishda uzatuvchi va qabul qiluvchi uchun nur burchaklari bo’lib α=1020| N uzatgich elementi va β=1020| N qabul qiluvchi. Qabul qilgichdan r masofada joylashgan shovqin tugunidan signalni blokirovka qilish ehtimolini hisoblaylik : (7)
(7:8)
Formulani ohirgi elementi CBrf(r) taqsimlanish zichligini hisoblashga o’tamiz:
(9)
bu yerda pL nuqtaning r radiusli aylanada bo’lish ehtimoli λπR2 – nuqta oqimi topilgan (4), (8) va (9) ifodalarni (3) ga almashtiramiz, keyin interfrensiyaning o’rtacha qiymati (10) formula bilan ifodalanadi:
