write a VHDL module to implement a circuit that can generate a clock signal whose time period is a multiple of the input clock. A control signal F determines the multiplying factor. If F=0 the output signal has a time period twice that of the input clock. If F=1, the output signal has a time period twice that of the input clock. The portion of the clock cycle when the clock is 1 may be longer than the portion when it is 0, or vice versa. Use a counter with an active-high synchronous clear input.
A new government law requires that the lead content of drinking water be less than 1.0 ppb. You are a safety engineer, and you have recently tested your companys drinking water using two methods. Method A gives a reading of 0.85 ppb
A 12 bit ADC with Vref of 5V is used to digitize a sinusoidal signal a quiescent value of 2.5V and a p-p amplitude that is restricted to 1.5V p-p. What is the ENOB of this ADC with this input signal due to quantization noise
Consider the logic function f(a,b,c) = abc + ab'c + a'bc + a'b'c + a'bc'. (a) Draw the logic circuit for the function f given above. (b) Let the cost of a logic circuit be the total number of gates plus the total number of inputs to all gates
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way using some device.
A pulse is used to measure the frequency response of a system. Since we expect the frequency response to extend to 20 kHz, select a pulse whose magnitude spectrum is constant within 1% out to 20 kHz.
How to find impendence in a series parallel circuit without using imaginary numbers. The circuit in question has a voltage source of 25 volts frequency is 100 Khz then the R1 resistor 220 ohms in series with an inductor
a 4-pole, 50 hz induction motor has a full load slip of 5%. each rotor phase has a resistance of 0.3 ohms and a standstill reactance of 1.2 ohms. find the ratio of maximum tirque to full load torque and the speed at which the maximum torque occurs..
The output of a communication channel is Y = X + N where X and N are independent, zero mean, random variables. X represents signal and N is noise. (a) Find the correlation coefficient between the input X and the output Y.
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
A charge of 4 micro-Coulomb is applied to the surface of the car. If the car travels a distance of 2 meter between the two electrodes, and if the mass of the car is 200 grams, then what is the approximate time taken by the car to reach the second ..
Write a function to compute the square root of a number based on Newton's method, but using a convergence criterion based on the difference between two successive iterates for the roots.
Assuming a 24 dB link margin is needed to account for fading and loss due to heavy rainfall on the longest link, while 12 dB link margin is sufficient for the shorter link, what transmitter powers are needed at each of the four transmitters
