Electricity and Electronics
3 original lesson summaries in this topic collection.
Topic overview
- Analogue signals vary continuously; digital signals use discrete levels and resist noise.
- Sample at least twice the highest frequency; n bits give 2ⁿ levels; bit rate = samples/s × bits.
- Modulation places information on carriers in allocated bands: AM varies amplitude, FM frequency.
- ASK, FSK, PSK and QAM are digital modulation methods; demodulation recovers the signal.
