Best way to go is separate dedicated lines for digital and analog equipment.
Definitely for a home computer.... They put filthy hash back out on the AC line.
Dedicated lines will decouple the power supplies from one another.
Digital equipment non linear switching power supplies put a lot of hash back out on the AC line in the form of odd harmonics an AC transients.
Take two dedicated branch circuits that are ,say, 50ft long each. Because of the impedance of the wire the switching power supply transient spikes will dissipate very fast in the branch circuit conductor on its way back to the electrical panel. Even a lot of the odd harmonics will end up out at the utility power transformer and be dissipated in the secondary winding in the form of heat. Not all....
If both digital and analog are fed from the same duplex receptacle from the same branch circuit the two power supplies are basically coupled together.
Good power cords on digital equipment that shield RFI/EMI can help from the hash coupling to the analog equipment.
A Sub panel can be fine provided the branch circuits fed from them are not too short.
