A common-collector (CC) amplifier is also known as an emitter follower (or a voltage follower) due to the fact that the output voltage "follows" the input by being approximately equal to the input voltage. The amplifier is shown in Figure (a), in which the collector forms a common terminal between the input and output circuits, and resistors R1, R2, and RE are determined by biasing. Capacitors CB and CE are chosen large enough to appear as short circuits at the lowest frequency of interest in the input signal vS. The output voltage vL is taken across the load resistor RL. The small-signal ac equivalent circuit of the amplifier is shown in Figure (b), whose analysis yields the following results:
a single phase 120 volts, 60hertz supply is connected to a coil of 200 turns wound round a toroidal magnetic core with a mean length 100cm and cross section 20cm square &relative p
Load Balancing and Load Management It has been observed in which the load on all three phases of a distribution line and between the feeders is not balanced. This output in in

A uniform quantizer is said to have 16 levels, and hence is called a midriser. The saturation levels are to correspond to extreme values of the message of 1 V ≤ f(t) ≤ 17 V. Find
When a machine has more than two poles, only a single pair of poles needs to be considered because the electric, magnetic, and mechanical conditions associated with every other pol
Q. A negative impedance converter is used, as shown in Figure. Show that the load current i L is given by v in /R, which is independent of Z L . Note that since the load sees a cu
