Final answer:
The statement that all modern amplifiers are digital and have replaced analog amplifiers is false, as both types are still in use today for different applications.
Step-by-step explanation:
The statement 'Almost all modern amplifiers are digital, having replaced earlier, analog versions' is false. While digital amplifiers are common in many applications due to their integration with digital systems, analog amplifiers are still widely used in various scenarios where the nuances of analog signals are important, such as in audio equipment and instruments. Both digital and analog amplifiers have their own unique applications, advantages, and disadvantages, and neither type has completely replaced the other.
