Two bit Analog -to -digital converter-MatLab (711)Let X(t)= 0.8 cos(2*pi*t)+ 0.15, 0<=t<=1, and zero otherwise, be the input to a 2-bit analog-to digital converter. The four level quantizer corresponding to the 2-bit ADC is define askDelta<= x(nTs) <(k+1) Delta --> x'(nTs) = kDelta k= -2,-1,0,1where x(nTs), found above, is the input and x'(nTs) is the output if the quantizer. Let the quantization step be Delta = 0.5. Plot the inpu-output characterization of the quantizer, and find the quantized output for each of the sample values of the sampled signal x(nTs).
What are two of the major considerations that factor in the design of a substation. Give a couple of examples of station layouts where these factors are clearly demonstrated. What typical grounding materials are used in substations.
1 Determine the inductive reactance (in ohms) of a 2 mH coil for: a-DC b-60Hz c-4Khz d-1.2MHz 2 Determine the frequency at which a 1mh inductance has the following inductive reactances: a-10-ohm b-4k-ohm c-12k-ohm
Three 150 kVA, 480V/4000V,60 Hz single-phase transformers are to be installed on a 4000V, 3-phase line. The exciting current has a value of 0.02 pu. Calculate the line current when the transformers are operating at no-load.
a certain radio frequency generator delivers a power level of 12 dBm. If this signal is amplified, calculate how many decibels of gain is required to produce a power of 20 dBm.
A step down transformer is supplied with 100 V on the primary, from a source capable of only 1 A. if the voltage on the secondary of the transformer is 20 V, what is the current available from the secondary
What do you believe would happen, if you removed the 220 ohm resistor from the circuit and connected the LED directly to the 555 integrated circuit. Are there any appreciable differences between labeled, calculated.
Design a common collector circuit using a npn silicon transistor having Beta=90 with Vcc=20 V The desired Q-point is Vce=14V and Ie=2mA
The system works as follows. When the main program starts to run, the microprocessor commands the A/D to convert. The microprocessor then sits in a dummy loop until the A/D interrupts, after it has completed the conversion and data is available.
A 32 channel TDM system samples messages at 8000 samples per second, uses 2 bits for frame synchronization and 8 bits per sample. What must be the highest frequency in the message spectrum to guarantee perfect recovery of the original signal
What is specific application or product that might involve the z-transform and how is it relevant in the application or design of the application or porduct
A 1.55 micro meter fiber-optic communication system is transmitting digital signals over 100 km at 2 Gb/s. The transmitter launches 2 mW of average power into the fibre cable, having a net loss of 0.3 dB/km.
With |V| = 100 V, the instantaneous power p(t) into a network N has a maximum value 1707 W and a minimum value of -293 W. Find a possible series RL circuit equivalent to N.
