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.
Amplifier figures of merit. In electronics, the figures of merit of an amplifier are numerical measures that characterize its properties and performance. Figures of merit can be given as a list of specifications that include properties such as gain, bandwidth, noise and linearity, among others listed in this article. Figures of merit are important for determining the suitability of a particular amplifier for an intended use.
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.
