Primes

• Amplification
  • Negative-feedback amplifiers

    This sourceInvention of the negative-feedback amplifier; shows feedback eliminates parameter uncertainty and stabilizes gain against component/temperature variation (gain varied <0.01 dB, modulation products 75 dB lower). SUPPORTS the negative-feedback-stabilizes-gain claims.

• Feedback
  • Feedback amplifiers (Black 1934) in signal processing use negative feedback to reduce amplifier nonlinearity and distortion; the trade-off is that gain is reduced unless open-loop gain is very high
• Homeostasis
  • … plant state $x$ → sensor $s(x) = \hat{x}$ → comparator $e = x_{\text{set}} - \hat{x}$ → controller $u = K(e, \ldots)$ → actuator → plant, with $u$ driving $\dot x$ toward the setpoint — the canonical structure Black (1934) crystallized for engineered systems in his Bell Labs paper on stabilized feedback amplifiers.

    This sourceInvention of the negative-feedback amplifier; demonstrates how feedback eliminates parameter uncertainty and stabilizes gain against component variations and temperature drift; foundational for precision analog electronics and control systems.
