PAL versus PLA
a. Briefly explain the main differences between PAL and PLA.
b. Why can a PLA implement more logical functions than a PAL with the same number of AND-OR gates? c. Why is a PLA slower than a PAL with the same number of AND-OR gates (of similar technology)?
Fading margin can be defined as the incremental Eb/N0, in decibels, required to provide a certain desired error probability in a fading channel as could be achieved with the same modulation technique in a nonfading channel. Assume that a bit-error..
You need to design a 1 to 8 demux with 4 bit inputs and output. design the architecture in gate level
For a low pass Butterworth filter, given a prewarped stop band edge frequency of 24621.468 radians/second and a prewarped pass band edge frequency of 2599.358 radians/second, if the gain at the edge of the stop band is -40 dB, calculate the filter or..
A group of small appliances on a 60Hz system requires 20 kVA at 0.85 pf lagging when operated at 125V (rms). The impedance of the feeder supplying the appliances is 0.01 + j0.08 Ohms. The voltage at the load end of the feeder is 125V (rms).
A collector modulated transmitter has a supply voltage of 48 V and an average collector current of 600 mA. What is the input power to the transmitter. How much modulating signal power is needed to produce 100 percent modulation
the hd cable signal send out is usually ranging between (1-25mv), with the frequency range from 1000Hz- 20Khz. An amplifier will gain 46 db will boost the signal before sending it through the cable connection.
A 20-cm length of wire moves at 15m/s in a constant flux density of 0.4T. The wire, direction of motion, and direction of the flux are mutually perpendicular. Determine the voltage induced in the wire segment.
For a particular amplifier connected in a feedback loop in which the output voltage is sampled, measurement of the output resistance before and after the loop is connected shows a change by a factor of 100.
A series-connected dc motor operates at 1400 rpm from a source voltage of VT = 75 V. The developed torque (load torque plus loss torque) is constant at 25 Nm. The resistance is RA + RF = 0.1 Ω. Determine the value of resistance that must be placed..
The first stage is a transconductance amplifier with an input resistance of 2k ohms, an output resistance of 100k and a gm=0.002A/V. The second stage is a voltage amplifier with an input resistance of 5k, an output resistance of 18 ohms and a volt..
