Suppose you have a set of 10 symbols. Assume that in an average text each symbol appears as frequently as any other. (i) What is the relative frequency of each symbol (ii) What is the entropy of this
Assume the ASCII code is used for each character with an additional parity bit (in the most significant bit position, at left). Each character in ASCII is using 8 bits. Even parity is used. What eng
For example, if you have the two 3-bit words 000 and 110, you know that the first word is correct (even parity), the second word is correct (even parity), the first column is correct (odd parity), t
If an amplifier has an internal resistance of 500O, what turns ratio must be used to get maximum power transfer to a load of 4O.
A parallel circuit contains four branches with resistors values of 4.7k, 5.6k, 8.1k and 10k. Which branch has the largest current flow
A matrix is basically a 2-dimensional array. Given an int matrix with m rows and n columns, write a function called display to print it in the matrix format. Write a complete program to test your fu
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.
A circuit designer claims this circuit will produce an output voltage that will vary betweeen +5 or -5 as Vg varies between 0 and 5 V. Assume op amp is ideal. A)Draw a graph of the output voltege Vz
Design a three-bit binary counter that iterates over the following states when X = 0 and repeats 000 010 110 011 101 001 100 111 When X = 1, the counter should go through the states in the reverse ord
many cell phone battery chargers operate on 2.4 volts, while others operate on 3.0 volts. The cell phone battery charger in use for this project is 2.4 volts , but it is broken and cannot charger th
Find the current change brought about by subjecting a 1 mH sinductance to a voltage pulse having an amplitude of 1V and a duration of 1 ms.
Heat is added until the final volume is twice the initial volume. Assume that Helium behaves as an ideal gas. Use the table provided to determine the specific heats of helium and determine the follo
A piston-cylinder arrangement whose piston is resting on a set of stops contains 0.5 kg of helium gas at 100 kpa and 25oC. the mass of the piston is such that a pressure of 500 kPa will just life it
Design a passive RC low pass filter with a cutoff frequency of 100Hz using a 4.7 uF capacitor. a) draw a schematic showing your filter while designating all component values and labeling the input and
Write a program for the dragon 12 so you can manipulate all four 7-segment LEDs:You will be able to enter any number or any sequence and be able to display them on the LED's each for one digit, and
An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt). a) Find the power of the modulated signal. b) Find the f
Consider a superheterodyne FM receiver designed to receive the frequency band of 88 to 108MHz with IF frequency 10.7MHz. The range of frequencies generated by the local oscillator for this receiver
What is the maximum output resistance that the source follower must have if the output voltage is to remain within ±20% of nominal value. If the MOSFET has kn = 16 mA/V2, at what current ID m
A compact disk (CD) records audio signals digitally by using PCM. Assume that the audio signal bandwidth equals 15 kHz. If the Nyquist sample are uniformly quantized into L=65,536 levels and then bina
Although sums behave like integrals, because of the discrete nature of the sums one needs to be careful with the upper and lower limits more than in the integral. To illustrate this, consider the se
Discuss how sampling theory provides the necessary information to convert a continuous-time signal into a discrete-time signal and then into a digital signal with minimum error. Discuss the paramete
