T{x1[n] +x2[n]} = T{x1[n]} + T{x2[n]} It is using linear to algebra to see if the system is linear. It has to be both have the additivity and homogeneous/scaling property

I have just started working with discrete time signals, more specifically various system properties. I am wondering if their is a discrete time system that is homogeneous but not additive? This is basically testing the linearity of a signal with the additive and homogeneous criteria.

I derived Planck's Law with respect to λ and treated T as a constant. My thoughts were that if I do this and find the derivative I can then set it equal to zero and this will give me an expression for λ(max)

Homework Statement By direct calculation, derive and expression for the wavelength λ(max) at which blackbody radiation intensity is a maximum [b]2. Homework Equations Planck's law for the intensity distribution of blackbody radiation as a function of wavelength λ and the blackbody...

I understand now thank you

im sorry where did you get the lna -lnb cause i am adding bt +(m/v0) inside the ln and i don't think you can separate the two into ln(bt) + ln(m/v0)..

Homework Statement Suppose that a neutron with with mass M and initial speed v0 is traveling through a material, such as graphite. As the neutron moves, it makes collisions with atoms in the material, so teh faster it is moving, the more collisions it makes per unit time. Another model of...

Homework Statement A thin rod of total length L has a nonuniform density given by λ(x)=ae^-bx where x is distance from one end of the rod. What is the moment of inertia of the rod for rotations around the end at x=0. Measuring from x=0 to x=L Homework Equations λ(x)=ae^-bx...
