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.
Pink noise, or 1/Æ, (one over frequency) is a low frequency wave-like pattern with equal energy in all octaves. a chart! (Yes that explains everything I'm sure.) Pink noise straddles the line between white noise and brown noise. White noise is entirely uncorrelated data, complete chaos, the snow on the tv screen. Brown noise is highly correlated data full of predictability. So pink noise is where the chaos of white noise and the order of brown noise meet. Some things send out the actual frequency of pink noise and some behaviors or patterns when tracked and put on a graph match up to the pattern of pink noise. I think pink noise sounds like a big waterfall. I'm listening to it right now. It's really good at drowning out the outside world, curing the ringing in your ears, or for just relaxing. Things with pink noise: wind; pulsating quasars; your heartbeat
