Study Notes
- Frequency modulation (FM) transmitters achieve higher efficiency by increasing power through Class C amplifiers.
- Noise primarily interferes with nonsinusoidal modulating signals.
- Pre-emphasis circuits amplify high modulating frequencies before modulation.
- A pre-emphasis circuit uses a high-pass filter.
- Selectivity in most receivers is achieved using crystal filters.
