We need to use asynchronous TDM and combine 50 digital sources. On average only 20% of the sources are active at any time. Each output slot carries 18 bits of data from each digital source. Also 8 extra bits are added to each frame for synchronization. The output rate measurement shows a rate of 2Gbps. Answer the following:
A) how many slots are in each frame
b) what is the size of an output frame (in bits)?
c) calculate the throughput at the output link
d) what is the rate of each input channel (in bps)?
e) the efficiency of this TDM multiplexing?
A control system is needed to control a small shopping center parking lot lighting system and the exterior lighting for the building. The design specifications require that the parking lot lighting and the exterior lighting turn on at dusk automat..
Increasing the number of SIMD processors to 15 (assume this change doesn't affect any other performance metrics and that the code scales to the additional processors)
Design I/O wiring to control forward and reverse 12Vdc motor using PLC OMRON CJ1M. Consider that the forward movement of the motor will be controlled by a forward button and the reverse movement of the motor will be controlled by a reverse button
Design a phase-lag compensator G_c(s) such that the static velocity error constant K_v is 50 sec^-1 without appreciably changing the location of the original closed-loop poles, which are at: \(s = -2 \pm j\sqrt{6}\)
Create an array, array1, that has the last 14 elements of which the first element is 49 and the last element is 10. THen using the colon symbol create a new array, array 2, whcih has 8 elements. the first 4 elements of array 2 are the 4th through ..
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.
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
Using the time independent one dimensional Schrodinger equation, find the expression of the allowed energy levels for an electron in infinite potential well of width Δz= L (i.e. solve the differential equation and apply B.C. to obtain En)
A 100 W bulb takes 0.833A and a 200 W bulb takes 1.67 A from a 120V source. If the two bulb were connected across a 240 V source, what current in amperes will flow through the bulbs?
what are two fundamental advances in the circuit theory that were developed in the 19th century in response to the challenges of telegraphy?
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communicat..
A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
