What is Digital Electronics? What are combinational circuits? Define binary logic. Define logic gates. Define Truth Table. What is Min term? What is Max term? Define K Map. Define duality property. State De Morgan's theorem
Determine the signal/noise ratio (Eb/No) in input of the receiver for each modulation format presented below if symbol error rate (SER) is required to be 10-^4 (use the coherent detection), for the solution the appropriate graphs can be used inste..
A cellular operator using the FDMA technique is allocated a total spectrum of 25 MHz. The system has a channel bandwidth of 60 kHz. It also uses a guard band of 20 kHz. Compute the number of channels that can be simultaneously supported in this wi..
A plant expansion is planned in which 4 morelarge 4-kV motors must be added to the system. The current switch gear can not supply all 10 motors, because both the switch gear bus rating and the transformer rating would be exceeded.
Find the discrete-time, pure prediction Wiener filter. - Determine and plot the PSD for the random sequence and the power transfer function.
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which the spherical radius is 40cm. Use Eq. 6.7 to estimate the worst-case varation in film thickness between the center and edges
Design a combinational logic circuit on a seven segment in sequential order. Include the "-" betwen the day and the month and the month and year. 1. Show the truth table of values using whatever seven segment display u have (cathode or anode)
A 10-mV signal source having an internal resistance of 100 k Ohm is connected to an amplifier for which the input resistance is 10 k Ohm, the open-circuit voltage gain is 1000 , and the output resistance is 1 k Ohm.
If the telephone instrument has a resistance of 200 ohms when off hook and represents an open circuit when on hook calculate the combined resistance of the local loop and the power source at the central office.
Develop a robust and cost-effective vehicle movement detector based on the concept of Doppler radar and construct a control circuit for supplying power to vehicle movement sensors and detection circuitry to measure the reflected signal.
For a first order low pass filter, with a cut-off of 2 kHz, how many decades and octaves would the frequency be if the attenuation was -58 dB. What would the frequency be at that attenuation.
Loop antennas are very common and are often used by amateur radio sites. In fact, the figure on the right is provided as an example what one may find when searching for loop antennas on the web.
find the z-transform for 1s2s1. i need the solution hand- written not with a software. the final result that i got
