$($b$)$If the signal is transmitted using a on$-$off scheme over an ideal channel and received using an ideal low pass

filter with bandwidth Bo $,$ what value of $($Eb$/$No$)$ is required to obtain a bit error probability of $10-6?$

$($c$)$ If No$=2$ x $10-6$ W$/$Hz$,$ find the received signal power and the signal amplitude A for both the polar scheme

and the on$-$off scheme
