Consider a discrete-time linear time-invariant system with impulse response h[n]. If the input x[n] is a periodic sequence with period N (i.e., if x[n]=x[n+N]), show that the output y[n] is also periodic sequence with period N.
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
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..
A 1.0 dc voltage source is connected across a 10 ohm resistor. What is the current through the resistor if (a) the voltage source is ideal (b) the voltage source has internal resistance 0.1 ohm (c) internal resistance 1.0 ohm
If a frame is damaged then in this network the receiver sends back a request for retransmission. (For simplicity, assume all these requests arrive back perfectly at the sender). What is the mean number of transmissions required to successfully tra..
1- Find the voltage across the inductor for t > 0 2- Sketch the voltage and the current as a function of time 3- Find the power ( in microwatts) at the terminals of the inductor when t = 200 ms
pressure limits of 10 kPa and 8 MPa, with reheat occurring at 4 MPa. The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3185 kJ/kg at the exit of the high-pressure turbine
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
An electron is bound in a one-dimensional infinite potential well with a width of 5Å. (a) Calculate the first three energy levels that the electron may occupy. (b) If the electron drops from the third to the second energy level
A double-A (AA) rechargeable battery is rated at 1.2V, 2100mAh (mili-amp hours) 1- how many coulombs of charge can this battery hold 2- how many joules of energy are stored in the battery
A dc machine is rated 5 hp with V_f = 240 V, V_a = 240 V, r_a = 0.63 ohms, and L_AF = 1.8 H. At rated condtions w_r = 127.7 rads/s and the total resistance of the field circuit is 240 ohms. a) Calculate the rated armature current.
Build a C++ code for vehicle sensing device. Code is required to embed in the device so that then it must sense the location where the vehicle is currently present. The device must be able to track the location of the vehicle for its owner
The voltage drops across three resistors in series are measured 10V, 15V, and 25V. If the largest resistor is 47 ohms, what is the value of the smallest resistor?
