Quizplus · Accepted Answer

All the statements provided are true. Monolithic IC amplifiers are indeed directly coupled or DC amplifiers, allowing for the amplification of very low-frequency signals. Televisions and radios use tuned amplifiers to select and amplify a specific frequency or band of frequencies from the broad spectrum of signals received. Audio amplifiers often use coupling capacitors to block DC components of signals, allowing only the AC components (the actual audio signals) to be amplified.
