On April 6, 1914, Hiram Percy Maxim proposed the formation of the American Radio Relay League.

✅ The correct answer is option D.
“Noise figure” is one critical parameter for determining the “quality” of a low-noise, small-signal, amplifier, and perhaps more importantly, the sensitivity of the overall receiver system. It is especially important for VHF (very high frequency) – and higher frequency – designs where most of the undesired “noise” (noise that masks or overpowers the desired signals) is generated internal to the electronics itself. In HF (high frequency) applications, atmospheric noise plays a much larger role in determining overall useful sensitivity, so a circuit’s “noise figure” is less important.

✅ The correct answer is option C.

✅ The correct answer is option D.

✅ The correct answer is option B.

As surprising as its age is, the Internet was born from the U.S. military’s need to construct a decentralized computer network that could withstand a nuclear war. The network was used and refined by universities throughout the 1970s and 1980s, but it wasn’t until 1992 that the Internet was made available to the general public.

✅ The correct answer is option D.
