Design a circuit to multiply two 2-bit numbers -a,b and c,d and produce a 4-bit product -w,x,y,z. Show the truth table and the equations.
A rectangular chip has a top surface of 0.5 cm by 2 cm cooled by air at 20 oC with h = 150 W/m2.K. There are also 16 connector pins, 1 mm wide, 0.5 mm thick, 6 mm long and k = 60 W/m.K attached to a circuit board at 30 oC.
The work function of platinum is 4.09ev what retarding potential will be required to reduce the photocurrent to zero in a photoelectric experiment with Pt electrodes if the wavelength of the incident light is 2440 angstrom
A manufacturer specification sheet lists the transfer function of a pressure sensor as 45±5% mV/kPa with a time constant of 4±10%. A highly accurate test system applies a step change of pressure from 20 kPa to 100 kPa.
Write and test a program for the EASy68k to input a string from the keyboard, convert all letters to uppercase and echo (output) the new string to the screen. Use a subroutine to perform the lower-to-upper case conversion.
The converter canreceive signals from 0 V to 5.0V. Design the electronic processorthat must be connected between the sensor´s output and thecomputer´s converter A/D input; so that maximum sensibility is obtained. Justify each single proposal you m..
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters: R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms. The motor is connected to a three phase, 440-V, 60-Hz supply.
A rectangular waveform has a 50% duty cycle (high for 1/2 acycle and low for 1/2 a cycle). It goes between two voltage levelsof -3 V (low) and +8 V (high), and has a period of100μs. a. Determine the Average voltage of this waveform.
Suppose a standard single-phase transformer that has a rating of a 15 kVA, 600V/120V, 60 Hz is reconnected as an autotransformer to obtain 600 V primary to 720 V secondary voltage ratio.
A compensated op-amp has an open loop low frequency gain of 10^5 and an open loop -3db frequency of 10 Hz. If an inverting amplifier with a closed loop low frequency gain of 100 uses this op-amp, determine the closed loop bandwidth.
An Air capacitor consisting of two closely spaced parallel plates has a capacitance of 1000 pF. The charge on each plate is 1 micro C. What is the potential difference between the plates. If the charge is kept constant.
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
Suppose a linear circuit contains a voltage source and a current source. When the voltage source is set to 10V and the current source is set to 10 mA, the output voltage is 1V. When the voltage source is set to 10V and the current source is set to..
