M-सरणी PSK:
m-सरणी PSK के लिए डिजिटल रूप से मॉडुलित वाहक पारित करने के लिए न्यूनतम बैंडविड्थ निम्नानुसार दी गई है:
\(B.W. = \frac{{{R_b}}}{{{{\log }_2}M}}\)
गणना:
\(B_m=\frac{{{R_b}}}{{{{\log }_2}M}}\) -----(1)
BPSK:
BPSK के लिए M = 2 तो,
\(B= \frac{{{R_b}}}{{{{\log }_2}2}}= R_b\) ------(2)
समीकरण 1 और 2 से;
B = Bm log2 M
