i)The data rate of a QPSK modulated signal is 100 kbps. Assuming rectangular pulse shaping, what is the first-null (main-lobe) bandwidth of the modulated signal?
ii) The data rate of a continuous-phase FSK modulated signal is 100 kbps. What is the minimum frequency separation that can maintain orthogonality between the two tones (sinusoidal carriers)?
Finding rms current through Capacitor and Inductor, A circuit consists of a sine wave signal generator and a reactive component (L or C). The output of the generator is a sine wave with a peak amplitude of 8.8 volts at a frequency of 10.0 kHz.
Ib is 15uA in a circuit where an NPN transistor has an Av of 75 and VCE is 10 when Vcc is 25 and Beda DC is 75 and the Ic is 1.125mA, What would Rc be, assuming Ve=0
What happens to an ECG signal when a triggered average is applied I can see from the graphs that the peaks directly before and after the triggered peak become more and more blurry, but I don't understand
A diode is connected in series with a 30-V rms source to charge a 12-V battery with an internal resistance of 0.1 ohm. Specify the series resistance necessary to limit the peak current to 2A. Estimate the time required to recharge a 10-A hr batter..
What is the blocking probability of the system in (b) when the maximum number of users are available in the user pool?
Identify the steps involved in the delivery of a letter from the sender to the addressee. How are these steps similar to OSI layers' functions such as addressing, routing, resource sharing, error checking, and connectionless vs. connection-oriente..
How is the problem-solving process different when programming in assembly language versus programming in ladder logic?
A single-phase, 60-Hz power will be transmitted through the transmission line Each subconductor's radius is 10 cm. There are two configurations, the first one is setting subconductors A and B as a bundle, and C and D as another bundle
A metal plate is subjected to tensile stresses of sigma x = 21 ksi and sigma y = 17 ksi. The corresponding strains measured in the plate are Ex=920 µE and Ey=620µE. Determine Poisson's ration v and the elastic modulus E for the ..
Determine the conductivity of silicon at T = 300 K if it is doped with donor impurity atoms at a concentration of 1.25*1016 cm-3. Assume that the electron and hole mobilities are 1350 cm2 / V-s and 480 cm2 / V-s, respectively.
one question: During each cycle, the velocity v (in mm/s) of a piston is v = 6t - 6t^2, where t is the time (in sec). Find the displacement s of the piston after 0.75 sec if the initial displacement is zero.
A room has four doors and four light switches (one by each door). Sketch a circuit that allows the four switches to control the light - each switch should be able to turn the light on if it is currently off, and off if it is currently on.
