The following MATLAB command has been used to perform offline filtering y=filter([0.8 -0.8],[1 -0.3],x); Where x and y are the input and output vectors, respectively. What is the transfer function of the filter
An experiment consists of tossing a fair coin four times in succession. What are the possible outcomes Now count up the number of outcomes with three heads. If the outcomes are equally probable, what is the probability of three heads
A) Write the KCL expression for this circuit and set it equal to zero. B) Find the voltage of Vo. C) Use your value of Vo. The final step is to use the inverse phasor-transform operation to transform this value.
Three branches having impedances of 3 + /4 O, 16 - /12 ft, and - / 4 ft, respectively, are connected in parallel. What are the equivalent (a) admittance, (b) conductance, and (c) susceptance of the parallel connection in millisiemens
The problem is a series circuit with the AC voltage of 50V at a phase angle of 0 degrees. Also the resistor has a resistance of 3 ohms. Xc = 5 ohms, X(L) = 9 ohms. All three components are in series. The frequency is 60 Hz.
For a circuit with resistor of 10 K ohm and a capacitor of 5 micro Farads, what is the time constant in second?
A Si p+-n junction has the following parameters at 300K: taup = taug = 10-6 s, ND=1015 cm-3, and NA=1019 cm-3. Plot diffusion current density, generation current (Jgen) and total reverse current (JR) as a function
Write a program that asks a user to input (one at a time) the four numbers to fill a 2x2 matrix. For each number entered, make sure the user knows which number is being entered.
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss at ..
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
As far as a direct compaison of mechanical switches vs. transistors used as switches, the transistor does have a measurable impedance when ON, and a mechanical switch does not.
