Derive the quantization formula of a sine wave.

Derive the quantization formula based upon the variance of a sinewave and the variance of distortion due to quantization. This is the signal to distortion (SDR) ratio for a quantized sinewave. A is the amplitude of the quantized sinewave and Delta is the quantization interval of the analog to digital converter, and the quant ...continues

If the speed of a car is a linear function of time in seconds and 10 is less than or equal to t for time is less than or equal to 30. if after each second the speed of the car increases by 5 feet per second and after 20 seconds the speed feet per second is 80 feet per second how fast is the car going after 30 seconds?

Inner products and Complex Hilbert Spaces

In a complex hilbert space, prove the following: < f|g > = ¼ [ ||f + g||^2 - ||f - g||^2 + i||f + ig||^2 - i||f - ig||^2 ]

Integrals : Rayleigh's Energy Theorem ( Parseval's Theorem )

Evaluate the following integrals using Rayleigh’s energy theorem (This is Parseval’s theorem for Fourier transforms). All integrals spans between –∞ and ∞. I1 = ∫ df / [α2 + (2πf)2] I2 = ∫ sinc2(τf) df I3 = ∫ df / [α2 + (2πf)2]2 I4 = ∫ sinc4(τf) df ...continues

How much would you be willing to pay for this bond?

A bond has par value of $1,000 and has a coupon rate of 14% with 20 years to maturity. If the required return (or market rate) is only 12%, how much would you be willing to pay for this bond?

Will this bond sell at par, a discount or a premium?

If a bond has a coupon rate of 8% but the required rate (market rate) is 10%, will this bond sell at par, a discount or a premium?
