Develop a low-pass RC filter to attenuate 0.5 MHz noise by 97%. Specify the crit- ical frequency, values of R and C, and the attenuation of a 400-Hz input signal.
For w=w0, compute the ratio of the amplitude of the voltage source over the amplitude of the voltage across the resistor,Q=|U|/V0, when V0=sqrt(2), C=8.2microF, L=7mH, and R=1.5kOhms. Is this ratio larger or smaller than one
A generator uses a coil that has 110 turns and a 0.475 T magnetic field. The frequency of this generator is 43.0 Hz, and its emf has an rms value of 230 V. Assuming that each turn of the coil is a square (an approximation)
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit firs..
A fair 6-sided die was tossed in a fair way 5 times. a. What's the probability of getting the sequence of outcomes 1, not 1, 2, not 2, 3 b. What's the probability of getting exactly two 6's in the sequence of 5 tosses
Two induction motors and one synchronous motor are fed fromthe same 3-phase, 480V bus. The following data pertains to the 3motors: Induction motor #1: 480V, 120 hp output, PF=0.78 lag,efficiency = 82% Induction motor #2: 480V, 100 hp output, PF=0.80..
a. What dopant should the engineer use to obtain the largest fraction of the boule with a doping concentration between 2 - 6 x 1014 cm-3 b. What is the range in resistivity values for this doping variation c. What is the weights of the dopant and Si..
Find the sample space for the experiment: Drawing bolts from a lot of 20, containing one defective D, until D is drawn, one at a time and assuming sampling without replacement, that is, bolts drawn are not returned to the lot.
Analysing an RF splitter and power levels, A splitter is a device that has a single input and several outputs. It is used to send a signal to several different locations
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
A 240kW 500 Volt 1750rpm separately excited dc generator has an overall efficiency of 94%. The shunt field resistance is 60ohms, and the rated current is 5amps. The I^2R loss in the armature is 0.023pu.
Three loads are connected in parallel across a single-phase source voltage of 240 V (RMS). Load 1 absorbs 12 kW and 6.667 kVAR; Load 2 absorbs 4 kVA at 0.96PF leading; Load 3 absorbs 15 kW at unity power factor.
Design a single-pole PIN diode switch operating at f = 8 GHz. A PINdiode has the following parameters: Cj = 0.03 pF, R(forward) = 0.2Ω, R(reverse) = 7 Ω, Li = 0.6 nH, Zo = 50 Ω. Find what type of connection, series or shunt, gives thegreatest ratio..
