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?
a sinusoidal voltage has a peak value of 15V, a frequency of 500Hz, and crosses zero with a positive slope at t=0.1 ms. write an expression for the voltage using a cosine function in terms of t and constant pi.
A series connected DC motor has R_F + R_A = 11.5 ohm and draws 1 A of current from a DC voltage source with V_T = 18 V while running at 1000 rpm. What is the speed and developed torque when drawing 0.75 A of current
A) Write the KCL expression for this circuit and set it equal to zero. B) Find the voltage of Vo. C) Use your value of Vo. The final step is to use the inverse phasor-transform operation to transform this value.
For the discrete signals defined as the following: x[0]=4, x[1]=1, x[3]=-1, x[n]=0 for all other integers n. v[0]=1, v[1]=-2, v[2]=3, v[3]=-4, v[n]=0 for all other integers n. Compute the convolution x[n]*v[n] for n
A current I = 15√2
An amplifier using balanced power supplies is known to saturate for signals extending within 1.2 V of either supply. For linear operation its gain is 500 V/V. What is the rms value of the largest undistorted sine-wave output available,
If the mechanical power sent out from the machine is 100 kW at a rotating speed of 90% of the nominal speed. Compute the slip of the machine and find the power dissipation due to the rotor winding resistance.
the purchasing power P of a certain unit of currency declines by 3 percent per year. Determine the time constant associated with the purchasing power of this currency.
A 240/40 volt transformer supplies two different secondary loads. One load (a) draws a current of 12 amperes at a lagging power factor of 0.94. The other load (b) draws a current of 12 amperes at a leading power factor of 0.94.
An analog signal has a bandwidth of 37 kHz and must be digitized in an ADC. The peak voltage is 7V and you need to maintain a resolution of 0.078V. Find the number of bits per sample and then
The coils on the rotor, 10 turns per coil, are connected in series through the slip rings so that at any instance of time there are 5 coil sides under each pole. What is the dc voltage from a full wave rectifier if this rotates at 1000 rpm
A parallel-plate capacitor has plates of very large extent such that the electric field is perpendicular to the plates. The plates are separated by a distance of 1mm, and a voltage of 100 V is applied to them.
