Question 8 1 pts A signal, $x_a(t) = 2.56 \cos(2\pi F_c t)$ (Unit: Volt), is digitized using a 10-bit 2's complement coding A/D converter. Here $F_c = 150$ Hz. Assuming that except quantization error, there is no other noise source in the system. Answer the questions below. If $x_a(t)|_{t=t_0} = 0.5$ V, the closest HEXDECIMAL number representing the signal at $t =$ to is O 0x64 O 0x100 O 0x32 O 0x200
