Hi,
I was reading Art of electronics, chapter 2: Some basic transistor circuits. In section 2.05 - Followers with split supplies, i find this paragraph little confusing:
Because signals often are "near ground," it
is convenient to use symmetrical positive
and negative supplies. This simplifies
biasing and eliminates coupling capacitors
(Fig. 2.17).
I have attached the Figure. Could somebody explain How using split supply simplifies biasing and eliminates coupling capacitors ?
