(a) In a binary ASK system, the noise power spectral density Sn(f)=10^-10 W/Hz and the bit rate = 100 kb/s. The bandwidth = 100 kHz and the received power = 0.4 mW. Find the Bit Error Rate.(b) It is decided to apply a Fast Hopping (FH) scheme on the above ASK system. The hopping is made over 12 channels of 100 kHz; or over 1.2 MHz bandwidth. The ASK signal hops 6 bands per bit period. Now a strong jammer randomly jams one of the 12 FH channels. Find the new Bit Error Rate in the presence of the jammer.
