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.
This report explains how noise is measured, distinguishes annoying sound levels from those that can lead to hearing loss, identifies what sources of noise are currently regulated by the federal government, indicates which federal agencies are responsible for setting and enforcing noise standards, describes the extent to which the standards limit noise, explains the role of state and local governments, and discusses relevant legislative activity in the 106 th Congress.
