... V(t) = V0 sin (2 pi f t). (Your calculator MUST be in radian mode!) V0 is called “peak” or “maximum” voltage. In the USA the period T = 1/60 s, so frequency f = 1/T = 60 Hz. (In Europe, it’s closer to 50 Hz). A simple circuit diagram for a light bulb (which is basically a resistor) plugged into the ...

... The transformer circuit shown in Figure 3 provides an all-passive method of converting the differential I and Q outputs from a QD series demodulator into single-ended outputs. Since this method is ACcoupled, it cannot be used in applications that require I and Q DC response. The DC-blocking capacito ...

Buck converter



A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
