If the temperature is below setpoint, the output will be on longer; if the temperature is too high, the output will be off longer. The third controller type provides proportional with integral and derivative control, or PID.
Noise figure. Noise figure (NF) and noise factor (F) are measures of degradation of the signal-to-noise ratio (SNR), caused by components in a radio-frequency (RF) signal chain. It is a number by which the performance of an amplifier or a radio receiver can be specified, with lower values indicating better performance.
SINAD contains the measured Signal in Noise and Distortion (SINAD) expressed in dB. SINAD is defined as the ratio of the RMS energy of signal in to the RMS energy of signal in less the energy in the fundamental. To compute the THD Plus Noise in dB, simply negate the SINAD in dB.
