A voltage V=10cos(2000*pi*t) is applied to a 100mH inductance. Find the complex impedance of the inductance. Find the phasor voltage and current, and construct a phasor diagram. Write the current as a function of time. Sketch the voltage and current to scale versus time. State the phase relationship between the current and voltage.
The cross section of a cottage 20 ft wide is an isosceles triangle. If the slope of a side is 1.75 and there is a second floor 9 feet above the ground floor,What is the angle at each tip of the cottage?
Determine the voltage required on the input of the amplifier to give the maximum output of 85 dBuV. If the signal level from the aerial is 5 dBmV and the input noise level is 20 dBuV, calculate the signal-to-noise ratio on the output of the amplifi..
The probability that a person will install a black telephone in a residence is estimated to be 0.3. Find the probability that the tenth phone installed in a new subdivision is the fifth black phone.
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
Consider a signal x(t) = 10 cos(2pi*fct + 4 cos 2pi*fmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when.
Interface binary Input Output devices to the microcontroller
Identify the types of system-building methods used by Dorfman to build its wireless warehouse system.
When the beam is not broken, light from the transmitter hits the receiver and turns on the output transistor from the receiver. Their purpose is to detect objects as the objects break the beam. design a through-beam photoelectric sensor
Sketch the Capacitance-Voltage characteristics for both devices based on part (d) by giving appropriate labeling to the voltage and capacitance axis. You may assume high f measurements.
An LVDT (Linear Variable Differential Transformer) is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31 mV/mm with a +/- 2 cm maximum core displacement.
Using nodal analysis solve for the current and supemode used to solve this circuit is located between which two nodes?
