Give a simple example of each of the following. If it is not possible to specify such an example, clearly state, in one or two sentences, why not:
(a) a random process that is SSS but not strict-sense or wide-sense ergodic;
(b) a random process that is wide-sense ergodic but not wide-sense stationary;
(c) a non stationary random process.
Show how, in an embedded system using a Gumnut core, the keypad controller of Example 8.3 and two instances of the ADC controller of Example 8.4, the components are interconnected using distributed multiplexers.
120V, 60 Hz source is connected to a distribution line whose resistance, and inductive reactance is 0.001Ohm, j0.002 Ohm, respectively. Single phase, 100HP, 120V, 0.85 pf. motor; and 100Kw, 120V heater are connected in parallel.
Design a combinational circuit that multiplies by 5 an input decimal digit represented in BCD.The output is also in BCD. Show that the outputs can be obtained from the input lines without usingany logic gates?
If the efficiency of the motor and drive system is 80% and it is fed through a transistor regulator at 12V, what is the mean current through this regulator when the printer is working continuously?
Three amplifiers with power gains of 15, 22, and 7 are cascaded. The input power is 120 µW. What is the output power of the final amplifier stage
A signal source produces a 4 volt peak-to-peak sinusoid and has a source resistance of 100 ohms. We wish to drive a grounded 10 ohm load to at least 2 volts peak-to-peak with this source. The load cannot tolerate DC. Your amplifier should not burn..
The resistivity of copper is 1.724 micro-ohm-cm at200C. Determine for copper at 200C the resistance (a) of a cylindrical conductor 1 meter long and having a diameter of 1mm; (b) a rod 2 meters long and having a diameter of 2mm.
Determine the signal/noise ratio (Eb/No) in input of the receiver for each modulation format presented below if symbol error rate (SER) is required to be 10-^4 (use the coherent detection), for the solution the appropriate graphs can be used inste..
Discuss the possible difficulty of such an approach.
Calculate the code word corresponding to the all-ones information sequence. Calculate the syndrome corresponding to an error in the third position assuming the code word corresponding to the allones input sequence.
a) what is the frequency f, of the ac circuit signal b) what is the period, T, of the ac circuit signal what is the angular velocity/frequency (omega), of the ac signal if v(t) = 24 cos (2pie 500t).
A full-wave rectifier is to be designed using the bridge circuit configuration. The peak output voltage is to be 9 V, the nominal load current is to be 100 mA, and the ripple voltage is to be limitedto Vr= 0.2 V.Assume Vγ= 0.8 V and let vI= 120√2s..
