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.
Hi Bixler, The critical word here is perceived. This is a 3 decibel (dB) difference which represents twice the amount of noise energy for the 76 over the 73 dB unit. HOWEVER, our hearing doesn't work like you would think.Twice the energy [also called power and sound pressure level (SPL)] does not sound twice as loud.In actuality, this is a BARELY noticeable difference. You would have to have both units side by side and run one then the other to notice the small difference.i Bixler, The critical word here is perceived.
