A synchronous (4-bit) up/down decade counter with output Q works as follows: All state changes occur on the rising edge of the CLK input, except the asynchronous clear (CLR). When CLR = 0, the counter is reset regardless of the values of the other inputs.
(a) Write a VHDL description of the counter.
(b) Draw a block diagram and write a VHDL description of a decimal counter that uses two of the above counters to form a two-decade decimal up/down counter that counts up from 00 to 99 or down from 99 to 00.
(c) Simulate for the following sequence: load counter with 98, increment three times, do nothing for two clocks, decrement four times, and clear.
Find I1 and I2 in the circuit of Fig. 13.84. Calculate the power absorbed by the 4-Ω resistor.
The power in watss disspiated by a resistor is given by P=IV. The resistors used are 1 watt resistances i.e. they are capable of dissipating a maximum of 1 watt without overheating. What is the maimum voltage that can be put across a 1 watt, ..
A logic circuit realizes the function F(a,b,c,d) =a'b'+a'cd+ac'd+ab'd'. Assuming that a = c never occurs when b=d=1,find a simplified expression for F.
Calculate the voltage drops across R1 and across R2. Measure total current for the circuit and compare it to your calculated value in step 1. Be sure to provide a screenshot displaying the measured result.
Fundamentals of Electric Circuits fourth edition: alexander, sadiku chapter 12 problem 12.29 A balanced three phase wye-delta system has Van= 120 angle 0 Vrms and Zdelta= 51+ j45 ohms. if the line impedance per phase is 0.4 + j1.2 ohms,
How do you draw a schematic of a circuir that implements any of the following: a circular left or a right shift of 0-3, or a logical left or right shift of 0-3
Starting from the expression for the MOSFET unity-gain frequency, fT=gm/2*pi*(Cgs+Cgd) and making the approximation that Cgs>>Cgd and that the overlap component of Cgs is negligibly small, show that for an n-channel device fT=3*un*Vov/4*pi*L^2
Compare the result with that of a cascode stage for a given bias current (IC1) and explain why this is generally not a good idea.
Derive the equation of motion for the system to obtain the mathematical model and experimentally obtain the parameters of transfer function of the pendulum system.
