A box contains 50 diodes of which 10 are known to be bad.
If the first diode drawn from the box was good, what is the probability that a second diode drawn will be good?
Consider a virtual memory system that can address a total of 232 bytes. You have unlimited hard drive space, but are limited to only 8 MB of semiconductor (physical) memory. Assume that virtual and physical pages are each 4 KB in size.
The transfer function of a circuit is given by H(s)=2 s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator. b. What is the characteristic equation o..
the transformer is to be connected as an auto transformer to supply a load at 120 V from a 210 V source. What kVA load can be supplied without exceeding the current rating of the windings (assume an ideal transformer for this part)
Power factor improvement, An industrial user has a number of machine tools which are driven by three phase induction motors. during a particular shift, the power factor of the combined load can vary between 0.65(100 KVA load) and 0.81 (20 KVA) loa..
Describe the phenomenon of aliasing caused by under sampling. How can aliasing be mitigated What are the advantages of digital communication over analog What is quantization noise How can you reduce it
Create the Walsh code matrix for a W16. (c) For IS-95, on the forward link, list the Walsh code assigned to the various logical channels (hint: there are 64 Walsh codes)
A terrestrial radio link transmits a CDMA signal from a base station using a spreading code with a chip rate of 1.0 Mchips per seconds. The message data rate of the signal is 10 kbps.
A three phase synchronous motor has the synchronous reactance of 2.1 Ohm and draws 250 A with a lagging power factor for an excitation voltage of 1327 -15 degree per phase. Find the terminal voltage of the motor and power factor of the motor.
Important information about System Analysis and Design, Elmwood College Situation: The school is considering a new system that will speed up the registration process.
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
What is the quantization signal to noise ratio SNRQ at the receiver output? e. If the SNRQ were to be raised to 96 dB, how many bits would the ADC and DAC need? What would be the bit rate on the serial link?
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
