1. Write a function that accepts a number t0 as input argument and returns the unit step function u(t t0). Your function should also create the graph of u(t t0) in a proper time interval.
2. Write a function that accepts a number t0 as input argument and returns the Dirac function d(t t0). Your function should also create the graph of d(t t0) in a proper time interval.
A small buck converter has 24 V input and 12 V output. The transistot has Rds(on) = 0.1 Ohms. The diode is modelled as a 1 V drop. Each device has Rtheta(ja) = 40 K/W and Tjucntion
What is the role of the secret key added to the hash function in Figure 31.17 in the text (MAC)? Explain.
Write a program to compute the impedance Z and the inductance L of an electrical coil, given the voltage V, current I (amps), resistance R (ohms), and frequency F (cycle/second). Make use of selection and conditional repetition.
Derive the circuits for a three-bit parity generator and four-bit parity checker using an odd parity bit.
A quantity of electric charge brings about the decomposition of 4.5 g Al from Al+3 at the cathode. How much volume (STP) of H2(g) from H+ at the cathode will be produced using the same quantity of electric charge?
use multisim or matlab to calculate the output signal v shown in fig. 3 use eq. 2 for your calculations. consider the
Find the potential and electric field intensity everywhere between the plates of the capacitor.
Given the following array declaration, if the array is stored starting at address 1000, what is the output of the following statement? Assume the code is for a 32 bit processor such as a Pentium.
What type of cable is necessary for each connection: straight or crossover? You can assume that S1 and S2 do not have the ability to resolve crossovers (called Auto-MDIX).
What would the rating of this transformer be if it were operated on a 50-Hz power system? Sketch the equivalent circuit of this transformer referred to the primary side if it is operating at 50 Hz.
When the base and collector supplies are equal, the transistor can be drawn as shown in Fig. 6-34b. What is the collector-emitter voltage in this circuit? The transistor power? (Give answers for the ideal and the second approximation.)
the bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12k
