AI Mentor for Electronics & Telecom Students

Every signal you decode today is one less static-filled doubt tomorrow.

An engineering student asks Sumantrak

“explain amplitude modulation for viva”

The message signal varies the amplitude of a high-frequency carrier while keeping frequency and phase constant — the envelope of the modulated wave traces the original message. Viva tip: be ready to draw the frequency spectrum (carrier + two sidebands) and explain bandwidth = 2×message frequency — that's the question after this one, every time.
