🔍 Key Concepts

• Basic radio transmitter block diagram (microphone, audio amplifier, modulator, RF amplifier, antenna) • Difference between audio (AF) stages and radio-frequency (RF) stages • Where modulation of the RF carrier by audio intelligence takes place

💭 Think About

• Look at the blocks and think: which one is the first point where a voice signal (from a microphone) would enter the transmitter path? • Ask yourself which block works with low‑frequency audio, and which blocks work with high‑frequency RF signals. • Consider which block’s job is to combine the audio intelligence with the RF carrier, and where the audio must be applied to do that.

✅ Before You Answer

• Identify which symbol in the diagram is associated with audio input or microphone rather than RF power or antenna. • Confirm which labeled block handles modulation (mixing audio with the RF carrier). • Make sure you are not selecting the RF output or antenna stage, since those already carry the modulated signal, not the original audio intelligence.
