ध्रुव-शून्य आरेख से:
- -3 पर एक शून्य
- (-1± j) पर संकुल संयुग्मी ध्रुव
- तब, एक नेटवर्क का चालन-बिंदु प्रतिबाधा Z(s) द्वारा दिया जाता है:
\(Z(s) = {s+3 \over (s+1+j)(s+1-j)}\)
\(Z(s) = {s+3 \over s^2+2s+2}\)
दिया गया है कि, DC लब्धि : Z(0) = 3
इसलिए, DC लब्धि मान 3 के बराबर प्राप्त करने के लिए Z(s) को 2 से गुणा करना होगा।
\(Z(s) = {2(s+3) \over s^2+2s+2}\)
