Consider a 16-ary PSK system with symbol error probability PE=10-5. A Gray code is used for the symbol to big assignment. What is the approximate bit error probability? Repeat for a 16-ary orthogonal FSK system.
A 1000V, 50 hp compound motor runs at a speed of 750 rpm at full load. The armature, series and shunt field resistances are 0.5 ohm, 1 ohm, and 200 ohm, respectively. The motor efficiency at this condition is 80%. Calculate the motors starting cur..
determine that the total field B within the sample is one tesla. Calculate M and determine what percentage of the volume now consists of domains with magnetization parallel to the field.
Consider a Si p-n junction at room temperature. If the doping concentrations are NA=1016 cm-3 and ND=1015 cm-3, what is the depletion width also known as space charge width Also find the maximum electric field.
A full-wave rectifier circuit having centre-tapped transformer has 500 turns in its primary winding, 25 turns from one end of the secondary winding to the centre tap and 20 turns from the other end of secondary winding to the centre tap.
A mixer stage has a noise figure of 20 dB. This mixer stage is preceded by an amplifier which has a noise figure of 9 dB and an available power gain of 15 dB. what is The overall noise figure referred to the input.
Develop the Boolean expression in POS form found by removing the static-zero hazards from the following expression. Your circuit must be minimized to receive full credit. Draw the schematic for the hazard-free circuit.
How do you create a class in Java to enable its object to be persistent What are Java data streams and how are they used to facilitate storage and retrieval of persistent objects
A circuit consists of two 1.0 k ohm resistors in series and this series being connected in parallel to a 570 ohm resistor. If the voltage drop across one of the 1.0 k ohm resistors is 4.5 V, what is the voltage drop across the 570 ohm resistor
Given a fiber optics line between Alaska and Oregon, with a data capacity of 2.5 Gbits/s, calculate the following: a. the number of voice channels (64 kbits/s each) that can be carried on this line b. the number of CDs per second (650 MB each) that c..
The operation of the watchdog timer is controlled by the 16-bit register WDTCTL. It is guarded against accidental writes by requiring the password WDTPW = 0x5A in the upper byte. What would happen if a value with an incorrect password is written t..
Consider a baseband transmission channel with a bandwidth of 10MHz. Which bit rates can be supported by bipolar line code and by Manchester line code
What is the symbol rate and what is the bandwidth occupied by the 16-QAM signal? The link must maintain a BER no higher than 10^-6. What is the minimum CNR in the receiver to meet this requirement?
