Answer: Teheh pls mark brainliest if you need to know how tell me
Explanation:
The number four on top says that there are four pulses to one bar, and the number four on the bottom says that these pulses are measured in terms of quarter notes.
Until computers started to dominate science and technology in the early decades of the 20th century, virtually every measuring instrument was analog.
Many scientific instruments now measure things digitally (automatically showing readings on LCD displays) instead of using analog pointers and dials.
Hope this helps!!^^ plz mark brianliest?
