The signal noise ratio in an FM system is 4:1 The maximum allowed deviation is 4 KHz. How much frequency deviation is introduced by the phase shift caused by the noise when the modulating frequency is 650 Hz? What is the real signal to noise ratio?
Design and implement a sequence detector using a finite state machine that detects the sequence 1, 1, 0, 1, 0. Consider previous/oldest bits for the sequence detection. Design the fuction using D-Flip-Flop
during winter you use an electric heater rated 1000W . heat transfer occurs through four walls each width of 5m and hight 3m layers of walls are concrete , paint, gypsum. temperature outside is 5 degrees celsius what is the temperature inside the ..
A transmission line operating at 125 MHz has Zo = 40 Ω, α = 0.02 (Np/rn), and ß = 0.75 rad/m. Find the line parameters R', L', C', and G'.
Design a differential input difference amplifier for a differental voltage gain of Ad=20. There are no stipulations for minimum or resistance values. What is the input resistance of the differential amplifier
Design the counter using D-flip-flops such that the state codes are the output values of the circuit. For example, when the circuit is in state 011, the output LED's display "off" "on" "on". Thus, no output equations need to be designed.
The return current is through the outer conductor, which consists of an infinitely thin cylindrical shell of radius b. Use Ampere's law to calculate the magnetic field intensity everwhere.
Sketch the baseband signals for the two users when user 1 sends the bits 011, and user 2 sends the bits 101. Add the signals for the first bit only, and show that the output of the correlator for user 1 is -4, corresponding to a 0
A cellular radio transmitter has a power output of 3W at 800 MHz. It uses an antenna with a gain of 3 dBi. The receiver is 5 km away, with an antenna gain of 12 dBi. Suppose that the transmission line losses are 1 dB at the transmitter
given a sequence x(n), where x(0) = 4, x(1) =3, x(2) = 2, and x(3) =1 with the last two data zero-padded as x(4) =0, and x(5) = 0, evaluate its DFT x(k)
A 4 pole 50 kW dc machine has a value of Ea = 110 V at 1100 rpm. What is the induced voltage is the speed is increased 20%. Note: omega(w) = (2f*n)/60 where omega is in rad/sec, and n is in rpm
consider an ideal amplifire with inverse feedback. explain what is meant by a virtual ground for both inverting and non-inverting connections
Assuming the input resistance of the load cell is 420 and rated output is 3.0mV/V at the rated capacity. What should be the series resistance that should be added to the excitation side so that the output voltage I reduced to 2.0mV/V
