Design a circuit that will indicate the birth months of February, April and May. The month is specified by a 4-bit input, A3:0. For example, if the input bits are 0001, the month is January and if the inputs are 1100, the month is December. The circuit should have one output that that is active when the input represents the birth month of a group member. For example, my birthday is in April so the output LED is HIGH when the input is 0100.1. Design your circuit two ways:a. Using a 4x16 decoder e.g. and necessary logic.b. Using an 8x1 MUX .
a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost
The motor driven by a switch-mode dc-dc converter, which has a bus voltage of 200V. The switching frequency fs = 25 kHz. Calculate and plot the waveforms for va(t), ea(t), ia(t), and id(t) under the following conditions
As typical in practice, the transformer taps are adjusted in steps, with each step changing the tap ratio by 0.625%. Because of the varying voltage drops caused by changing loads. LTCs should be operated to regulate the bus voltage.
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
The flux through the window of a 20-turn coil varies with time in the following manner: flux=1.2 sin(28*t) Wb. Determine a) the frequency and rms value of the voltage generated in the coil, b) the equation representing the voltage wave.
Design a 4-bit decrementer using Half-adders and inverters as building blocks. The circuits impleents A-1=S. Draw the circuit diagram. Hint: consider addtion of the 2s complement of -1 =1111. Begin with a 4-bit adder circuit constructed with 1-bit..
An SSB generator has a 9 MHz carrier and is used to pass voice frequencies in the 300- to 3300-Hz range. The lower sideband is selected. What is the approximate center frequency of the filter needed to pass the lower sideband
Assume that you have a CMOS inverter with a perfectly symmetric voltage transfer curve (VTC). What will happen to the VTC if you size down the NMOS transistor
Determine the output of the system described by the following difference equations with input and initial conditions as specified: y[n]+6y[n-1]-16y[n-2]=3x[n] x[n]=((-1)^n)*u[n] y[-1]=2 y[-2]=-1
Compute the power absorbed by an element in a circuit, but for a simple sinusoidal current i = sin(2πt/T) where T = 1 s.
A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 60.0-gram mass is attached at the 27.0-cm mark, the fulcrum must be moved to the 39.2-cm mark for balance.
Suppose that the amount of a weekly bill of all households is distributed with a mean of $140 and standard deviation of $35. Let X var be the average amount of bill of a random sample of 49 households selected.
