A multitone test signal consists of a sum of four 1.0-V RMS sine waves, one at 1.3 kHz, another at 2.1 kHz, another at 3.2 kHz, and the fourth at 5.3 kHz. Determine the frequencies of second-order and third-order intermodulation frequencies.
Metal sphere 1 has a positive charge of 8.0 nC. Metal sphere 2, which is three times the diameter of sphere 1, is initially uncharged. The spheres are then connected together by a long, thin metal wire. What are the final charges on each sphere
Describe one to two ways that you encounter and utilize electromagnetic radiation in your daily life. Note: Feel free to include both naturally occurring examples, as well as any man-made technologies.
A square wave signal with voltage levels 0 volts and 2.0 volt at a frequency of 1.00 MHz is multiplied by a sine wave at a frequency of 5.0 MHz
derive an expression for the maximum allowable amplifier noise figure F, assuming an amplifier gain G and a connecting line loss L. Evaluate this expression for

What will be the direction of rotation of a shaded pole single phase induction motor?
Exp.5Class A BroadBand Amplifier BAsed on the circuit shown: R1 = 68K?, R2 = 10K?, R3 = 10K?, R4 = 200? ( two 100? in series ),
Calculate each (3) superposition voltages at VO. The sum of these voltages will be VO with all 3 supplies connected.
Using the message signal m(t) = 1/(1+t^2) , determine and sketch the modulated signals for the following methods of modulation: (c) SSB modulation with only the upper sideband transmitted. (d) SSB modulation with only the lower sideband transmitted.
a stone is dropped into a river from a bridge 42.8 m above the water. another stone is thrown vertically down 1.46 s
A long wire having a linear charge density of 116 nC/m lies parallel to the y axis and intersects the x axis at 2m.
Consider a hollow cylinder with a length L along the z-axis and a radius R and a charge -Q, containing a wire also of length L and charge Q running co-axially to the cylinder at its center.
