Suppose a 3:8 decoder is attached to an array of 8Kx8 memory chips, the low 13 bits of the address access the locations within each memory chip, and the most significant 3 bits of the address are tied to the select inputs of the decoder (A15 is MSB and A13 is LSB.) Give the range of memory addresses (in hex) associated with the memory chip enabled by decoder output Y6.
The feedback capacitance of an inverting amplifier is 10pF. What is the Miller capacitance at the input if the gain of the amplifier is -120 What is the Miller capacitance at the output of the amplifier
ELF communication signals ( f
A sequential circuit hast two inputs (w1 and w2) and one output (z). Its function is to compare the input sequences on the two inputs. If w1 = w2 during any four consecutive clock cycles, the circuit produces a z=1; otherwise, z=0.
The bandwidth of a series resonant circuit is 400 Hz. (a) If the resonant frequency is 4000 Hz, find Q. (b) If R = 10 ohm, what is the value of XL at resonance
Explain the difference between TDM and TDMA.
Your embedded systems application requires you to implant a sensor in each of the taxiways of the airport and connect the sensor wires at the base of the ATC tower. The worst case distance is two miles.
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
Design a full wave unregulated dc power supply having an input of 220 V rms 60 Hz and an output voltage maximum of 19.5 V and a minimum of 15 V. This power supply will be needed to provide power to a load which requires a maximum current
Design a load resistor (resistance rating and power rating) network to have the transformer operate at full load. Design a second network for half load. You may need to combine several resistors to get the desired value.
Assume that this whole system is linear, so that, if the pressure on a sprinkler is halved, the area covered (as well as the flow rate) will be halved. This is true until the pressure is reduced below 20psi, at which it does not work at all.
A line charge of infinite lenght lies along the z axis and carries a uniform linear charge density of ρl C/m. A perfectly conducting cylindrical shell, whose axis is the z axis, surrounds the line charge.
A 50HP single phase motor operates from a 480V, 60HZ supply. When delivering full rated power the motor efficiency is 89% and the power factor is 0.78 lagging. Determine the full load current.(Hint: 746W=1HP)
