The i-v characteristic of a semiconductor diode designed to operate in the Zener breakdown region is shown in Figure P8.39. The Zener or breakdown region extends from a minimum current at the knee of the curve, equal here to about -5 mA (from the graph) and the maximum rated current equal -90 mA (from the specification sheet). Determine the Zener resistance and Zener voltage of the diode.
What is the resolution of an ADC with a word length of 12-bits and an analogue signal input range of 100 V A sensor produces a maximum analogue output of 5V. What word length is required for an ADC if there is to be a resolution of 10mV
Assume that a given transformer is 100% efficient; that is, the power being supplied by the primary side is transported without loss to the secondary side. (Transformers are not 100% efficient. One can detect this by the heat that they radiate.)
Suppose you have an Analog-to-Digital Converter (or ADC) with 12 bits of precision, and the manufacturer claims it has the transfer function x = floor(4096×v/5 ) for input voltage vΣ [0, 4.9999] (where x is the digitized result you get).
desgin a four-bit combinational circuit 2's complenmter.(the output generate complement of the input binary). then construct truth table for the input and correspondinf output. use kmap to find each outpt in terms of of inputs.
What is the minimum value for each of the individual decoupling capacitors?
In your own words, describe why makeup water, chemical additives to the makeup water, and blowdown are necessary in this process. Speculate on the probable disadvantage of making the I/H2O ratio in the blowdown (i) too small, and (ii) too large.
The problem is a series circuit with the AC voltage of 50V at a phase angle of 0 degrees. Also the resistor has a resistance of 3 ohms. Xc = 5 ohms, X(L) = 9 ohms. All three components are in series. The frequency is 60 Hz.
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
Determine the total charge entering a terminal between t=1 and t=2s if the current passing the terminal is i= (3t2-t)A.
A 460-V, three-phase,60-Hz system supplies power to a 10-kVA, delta-connected resistor load; a 50-kVA, 0.86 power factor induction motor, and a wye-connected synchronous motor that is operating at 0.62 power factor leading
