Logic gates are usually electronic circuits (based on anintegrated circuit) and they are used to make simple decisions. Agood example of this type of circuit is based on the 4081 Bintegrated circuit (IC). Research this gate design a circuit, usingit, to build the following.A dog owner wants to build an automatic animal feeder to workwhen his dog presses a switch (pressure pad). This type of devicewould automatically feed the dog when the dog presses a pressurepad (switch).a) Draw the thuth table for the logic circuit described above.b) Draw the diagram of the logic circuit described above.c) Show and explain the logic states of inputs and outputs.
design the sign extension component of an I-Format Data Path Unit, where a 16 bit number will be extended to a 32-bit number, while mainintaing the sign (signed numbers use 2s complement).
R- 1k ohm; L=1nH for the circuit represented in Fig. 8.1, and with the knowledge that i(0) = -3mA: a) Write an expression for i(t) valid for all t>=0 b) Compute i(t) at t=0, t=1ps, 2ps, and 5ps
When a square wave with a fundamental frequency of 2khz and amplitude 5v and comprised of up to five odd harmonic (each successive odd harmonic having half the amplitude of its predecessor) is passed though a standard telephone line of bandwidth o..
Construct a Phasor Diagram to represent the source voltage, source current, voltage drops, VR, and VL across the resistor and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be includ..
Consider an air compressor operating steadily. How would you compare the volumetric flow rates of the air at the compressor inlet and outlet. Will the temperature of air rise as it is compressed by an adiabatic compressor.
Show that a linear dependent current source controlled by a voltage appearing across an element in parallel with the dependent source is equivalent to a resistor. Determine the value of the resistance in terms of the parameters of the dependent so..
Two amplifiers are cascaded, one with a voltage gain of 6 db and the other with a voltage gain of 4. if 1 V is applied at the input of the first amplifier, what is the voltage at the output of the second amplifier
a high power FM station of frequency 96.9 MHz has an antenna height of 1200 feet. If the signal is to be recieved 60 miles from the station, how high does the listener need to mount their anntena in this fringe area
A certain magnetic core has a core loss of 8.4 W, of which one-third is eddy current loss, when the magnetizing field is changed 60 times a second. determine the core loss if the magnetizing field is changed only 50 times a second.
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.
Derive an expression for the optimum value of the avalanche gain opt M for which the signalto-noise ratio (SNR) becomes optimum by using the following expression for the excess noise factor: Fa( M)=KM+ (1-K ) (2-1/M). Assume that M^3 >> M .
Consider a digital filter with frequency response: H(f)=11+f Assuming the sampling frequency is 1500Hz what is the frequency attenuation of a signal passing through this filter at 280Hz
