Show the Probability density function and cumulative probability function of a sinusoidal random variable.
In a unity feedback system, the forward path has a transfer function of the form G(s) = k/(1+s/ωp), and the feedback path has a gain of kfp which is less than unity. Calculate the bandwidth of the closed-loop transfer function.
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication. The AWGN single-sided power spectral densit..
A series RLC circuit has a resonant frequency of 40 kHz and the Q is 20. At what frequency will the phase angle be 45 degrees
a) A personal computer with a monitor and keyboardrequires 60 W at 110V (rms). Calculate the rms value of the currentcarrried by its power cord. b) A laser printer for the personal computer in (a) is ratedat 80W at 110V (rms).
(The output generates the 2's complement of the input binary number) Show that the circuit can be constructed using Exclusive-OR gates. Can you predict what the output functions are for a 5-bit 2's complement
Design three voltage divider networks to achieve the following design criteria. With Vin = 10V, Vout should be within the range of 3.3 and 5V.
Find the input torque to the generator.If armature current and field current are kept constant, find the new value of the terminal voltage if the power factor is changed to 0.7 lagging.
An analog signal ranging between 0 and 1 V must be quantized. The midrange quantization errors must be no greater than 0.1V. How many quantization bits must be used to satisfy this requirement
A common-emitter amplifier with an emitter resistance RE, but without an emitter by-pass capacitor CE is good for high input resistance, common-emitter amplifier using an emitter by- pass capacitor is good for high voltage gain
Input resistance Rin=20K When fed from a signal source with a peak amplitude of 0.1v and a source resistance of 20k , the peak amplitude v(pi)is 5mv. specify Re and bias current Ic. The BJT has beta =100.
1) A steel cable 1.25 inches in diameter and 50 ft long is to lift a 40,000 lb weight. What is the length of the cable during lifting? The modulus of elasticity of the steel is 30x106 psi.
