One step in decoding a simple code without knowing the coding scheme , involves counting the number of occurrences of each character. Then, knowing that the most common letter in English is "e" the letter that occurs most commonly in the coded message is repeated by "e". Similar replacements are then made based on the number of occurrence of character in the coded message and the known occurrences of character in the English language. This decoding often provides enough of the correct replacement that the incorrect replacement can then be determined. Write a program that reads a data file and determine the number of occurrence of each of the characters in the files. Then, print the character and the number of times that they occurred.If a character does not occur, do not print it.
Using the commonly available resistors, capacitors, and inductors, design a critically damped series RLC circuit (i.e., all three components are connected in series) with an undamped natural frequency of 20 krad/s.
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
build a cicuit that must be able to operate a 3 amp load of the LED while being able to operate at voltages around 3V or 6V. It must be able to keep the LED on constantly while also being able to pulse the LED.
By that I mean, how does IM/IT help KL carry out day-to-day operations and transacting, how does it aid management processes, and does it enable KL product and service innovation?
Discuss how can identify which resistances are in series and which ones are in parallel in a series-parallel circuit. How might this affect how you measure current and voltages in the circuit with a digital multimeter
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
Derive the dynamic model and average value circuit of a buck converter assuming the ESRs of the inductor and capacitor are not equal to zero.
Define static electricity and State five sources of static electricity and Describe three methods used to reduce hazards due to static electricity
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A.
Solar Cell Consider a GaAs PN junction solar cell with the following parameters. Na=10^17 cm^-3, Nd= 2*10^16 cm^-3, Dn=190 cm^2/s, Dp=10 cm^2/s, Tn0=10^-7s, and Tp0=10^-8s.
A video signal contains light variations that change at a frequency as high as 3.5 MHz. What is the minimum sampling frequency for A/D conversion?
determine the equivalent impedance of the transformer referred to the high side (assume the equivalent resistance is negligible). Hint: draw a phasor diagram showing I E V and the impedance drop.
