1. Transducer
2. Pulser and Beam Former
3. Receiver
4. Display
5. Storage
6. Master Synchronizer
5 operations that must be performed in the appropriate order for the system to function properly:
1. Amplification
2. Compensation
3. Compression
4. Demodulation
5. Reject
The most common way to improve signal-to-noise ratio
Increasing output power
