ASK, PSK आणि FSK साठी त्रुटीची शक्यता खालीलप्रमाणे दिली आहे
\(P_{e_{ASK}} = Q ( {{\sqrt {\dfrac {A^2_c T_b \space }{4N_0}}})} \space \)
\(P_{e_{PSK}} = Q ( {{\sqrt {\dfrac {A^2_c T_b \space }{N_0}}})} \space \)
\(P_{e_{FSK}} = Q ( {{\sqrt {\dfrac {A^2_c T_b \space }{2N_0}}})} \space \)
Q(x) हा घटणारे फलन आहे म्हणून x वाढल्यावर Q(x) चे मूल्य कमी होते
\( \sqrt {\dfrac {A^2_c T_b \space }{N_0}} \space > \space \sqrt {\dfrac {A^2_c T_b \space }{2N_0}} \space > \space \sqrt {\dfrac {A^2_c T_b \space }{4N_0}} \space \)
म्हणून,
\( Q (\sqrt {\dfrac {A^2_c T_b \space }{4N_0}}) \space > \space Q(\sqrt {\dfrac {A^2_c T_b \space }{2N_0}}) \space > \space Q( \sqrt {\dfrac {A^2_c T_b \space }{N_0}}) \space \)
Pe ASK > PeFSK > Pe PSK
ASK मॉड्युलेशन पद्धतीत त्रुटीची जास्तीत जास्त शक्यता असते.
