A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. They serve the same function as an electromechanical relay , but solid-state electronics contain no moving parts and have a longer operational lifetime.

This is useful when sudden turn-on in the middle of a sine-wave half-cycle could cause undesirable effects like high-frequency spikes, for which the circuit or the environment is not expected to handle gracefully. The point where the AC line voltage is zero is the zero cross point. When a TRIAC is connected in its simplest form, it can clip the ...
Wage growth, an important measure for gauging inflation pressures, rose 0.4% in November, in line with October's increase and higher than the 0.3% rise economists had expected.

Doing this in only two clock cycles requires careful coordination between the time the SDRAM takes to turn off its output on a clock edge and the time the data must be supplied as input to the SDRAM for the write on the following clock edge. If the clock frequency is too high to allow sufficient time, three cycles may be required.
