Answer:
a) True
An unbalanced interface can have one of its signal conductors connected to ground, which is often the case in audio connections like unbalanced audio cables (e.g., RCA cables) where one conductor carries the signal, and the other is grounded. This design is susceptible to noise interference compared to balanced interfaces. However, unbalanced connections are still commonly used in various applications, especially for shorter cable runs where noise is less of a concern.
