If each packet carries 1000 bitsof data, the distance between the sender and receiver is 5000km,link speed is 1Mbps, and the propagation speed is2x108 m/s. Assume no data or control frame is lostor damaged. Ignore transmission time for ACK.a) How long does it take to send 1million bits of data if using Stop-and-Wait ARQ Protocol?b) Repeat for Go-back-N ARQ Protocol if using 3-bit sequence number.c) Repeat for Selective-Reject ARQ Protocol if using 3-bit sequence number.
It is necessary to determine the specific heat of an unknown object. The mass of the object is 170.0 g. It is determined experimentally that it takes 20.0 J to raise the temperature 10.0° C. Find the specific heat of the object.
design a third-order Butterworth highpass filter with fc=100 Hz and high frequency gain of 20 dB using the standard form of the third-order Butterworth polynomial (s+1)(s^2+s+1)
In a series RC circuit, R = 5 Ohms and C = 0.1F. The capacitor voltage is 10 volts at t=0. At t=0, a voltage of 4V is applied. a) Determine the total capacitance voltage and capacitance current as a function time after the external voltage is applied..
From a simple pn junction diode, predict the expected relative magnitudes of ac capacitances in a bipolar junction transistor under normal operating conditions(base emitter junction forward biased and base collector junction reverse biased).
Design the base-emitter area of NPN BJT so that its transconductance gain is gm=2 A/V at VBE=0.70 V. The technological parameters are as folows: the emitter is heavily doped, the base doping is 5*1017cm-3,the base width is W=0.5μm
a circuit for an ac voltmeter utilizes a moving-coil meter that gives a full-scale reading when the average current flowing throught it is 1mA. The moving-coil meter has a 50-ohm resistance.
Determine the output voltage of an op-amp for input voltages of Vi1=200uV at Vi2=140uV. The amplifier has a differential gain of Ad=6000 and the value of CMRR is A. 200 b. 10^5
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?
SR flip flop from D Flip flops, Show how to build a rising edge triggered SR flip-flop using a rising edge triggered D flip-flop and combinational logic.
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Perform experiments using your circuit design. Using your digital scope, plot (and submit) input voltage and output voltage from your circuit design. Try to vary the filter portion (R, L, C) of your circuit and plot (and submit) output voltages.
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
