Indicate whether the following statements are TRUE or FALSE with correction:

i$.$ To increase the channel capacity, you should focus more on increasing the SNR than increasing

the channel bandwidth.

ii$.$ Binary PSK is a differential analog signal, digital data encoding scheme.

iii. Variable bit rate $($VBR$)$ video traffic lends itself to packet switching.

iv$.$ The main advantage of biphase techniques is its low bandwidth requirements compared to the

NRZ family.

v$.$ Differential encoding is more reliable compared to non$-$differential encoding.
