For the situation described in P3.42 above, a modified design is required for the situation in which the supply variation is ±.5%. the Zener-diode nominal voltage variation is ±.3%. and the load variation is from 2 to 10 mA. Find the value of R for which the minimum Zener current is 2 2 Irs. For this situation, what are the limits on the output voltage produced? Assume rz = 20 0 and fa la 0.2 inA for all available senors.
A modulating signal consists of two sinusoidal components: 1 kHz and 3 kHz. The transmitter carrier frequency is 80 kHz. Assume in a SSB-USB modulated signal that the inserted carrier at the receiver is 200 Hz too high.
discuss some of the advantages of plcs over relay logic circuits. how do we decide to use either a plc or a relay
The voltage across an element is 12e to the power of -2t . The current entering the positive terminal of the element is 2e to thepower of -2t . Find the energy absorbed by the element in 1.5 s starting from t=0
The voltage V across a semi conductor in a computer is given by V= aI+BI^2, where I is the current (in A). If a 24 V battery is conducted across the semi conductor, find the current if a=4 ohms and B= 0.5 ohms/A.
Suppose a cache can satisfy a processor request in 5ns if it has a hit; otherwise the memory access time of 20ns must be added to the hit time. What is the average access time seen by the processor core for instructions for miss rates of 5%, 2% an..
A student has a coil of unknown inductance and resistance. He connects it in series with a 100 ohm resistor, places a voltmeter across the resistor, and connects the whole circuit to a power supply. When the power supply is 60 V DC
