Question: Show that the precision of estimating the mean does not change with the sampling frequency. Also show that the precision of estimating the standard deviation increases with the square root of the sampling frequency in contrast.
Design a circuit that will indicate the birth months of February, April and May. The month is specified by a 4-bit input, A3:0. For example, if the input bits are 0001, the month is January and if the inputs are 1100, the month is December.
Derive the expression for the friction torque in ?at collar bearing considering uniform pressure and uniform wear.
A thermoelectric switch composed of a copper rod 10 cm long at is to touch an electrical contact at a temperature of. What distance should there be between the rod end and the contact at?
Show a flowsheet program that represents the peak correction value used in the measurements system.- Use block diagram.
Because of the commutation problem, the field flux can be reduced down to one-third of the rated value. It is assumed that the field flux is proportional to the field current.
Describe why interrupts are not appropriate for implementing synchronization primitive in multiprocessor systems.
Give the truth table and the logical expression for a circuit with three inputs and one output. The output generates even parity for inputs. Use EXOR/EXNOR in the output expression when possible.
derive the design equations for R1 and R2 for each circuit. If Z0 = 50 Ω, compute R1 and R2 for 3, 10, and 20 dB attenuators of each type.
An amplifier produces a sinusoidal signal of 8.5V peak acrossa 50-ohm resistive load. the amplifier is powered from a 12Vvoltage source. a) What is the signal power delivered to the load
A dc-to-dc converter has an input voltage of 5 V and an output voltage of 12 V. If the input current is 1 A and the output current is 0.25 A, what is the efficiency of the dc-to-dc converter?
A DC electric motor draws a current of 8 amps, at a voltage of 50V. The efficiency of the motor is given as 60% at a a spindle speed of 400 rpm. Calculate the torque produced by the motor.
