Every waveform you understand today is one less static-filled doubt tomorrow.
A diploma student asks Sumantrak
“explain the difference between analog and digital signals”
An analog signal varies continuously over time, like a smooth sine wave — it can take any value. A digital signal only takes discrete values, typically just two (0 and 1), represented as distinct voltage levels. Viva tip: examiners like asking why digital is preferred for modern communication despite analog being how signals naturally occur — digital signals are far more resistant to noise since a receiver only has to distinguish between two levels, not reconstruct an exact continuous value.
