Signal theory is the theory of the engineering discipline of signal processing. It provides mathematical approaches for use in a wide range of applications. Fields as far apart as statistical physics and op-amp electronics share some of this material.
High-level aspects include:
• Amplitude
• phase
• resonance
• Q (Q for "quality", means the strength of a resonance)
• time constant (of a filter)
• great-signal and small-signal bandwidth
• maximum output swing
• noise floor
