A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below:
a) VI changes +2.0 V, ILoad constant
b) ILoad changes +100 mA, VI constant
Given: VZ = 6.8 V at IZtest = 5 mA, assume rz = 15-ohm and is constant over IZ
Consider a digital communication system in which the received symbol y is equal to : y = x+I+n, where n is AWGN with variant sigma_n^2, I models interference independent of both x and n and x is the data taking values +A and -A.
why sinusoidal wave is chosen for AC fundamentals rather than a simple curve such as square or triangular wave?
1. Calculate the total (composite) load power factor, true power, reactive power and apparent power. 2. Also calculate the full-load current and the amount of capacitive KVAR needed to bring the overall power factor to .95 lagging.
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..

Suppose the field to be imaged contains 3 parallel bars of width W mm, spread nonuniformly, with the darkness profile. Determine the darkness profile of the bars after imaging. Can you still tell all the bars apart
Develop a Sensor Circuit using commodity components and design a wireless sensor node using commodity wireless modules
A certain 11 V dry-cell battery, completely discharged, requires a current of 100 mA for 1.2 hr to completely recharge. What is the energy storage capacity of the battery, assuming the voltage does not depend on its charge status?
The EPROM should be mapped in a single block starting at address 0000 hex and the RAM should be mapped in a single block starting at address 8000 hex. 8051: Hardvard architecture with separate control busses for code and data memory.
