In MATLAB, the unit step function can be represented using the heaviside function, which returns 0 for negative inputs and 1 for zero and positive inputs. The impulse function, or Dirac delta function, can be approximated using the dirac function in the Symbolic Math Toolbox or by creating a discrete representation, such as an array with a value of 1 at a specific index and 0 elsewhere. Both functions are commonly used in signal processing and control system analysis for modeling and simulation. For plotting, you can use stem for discrete impulse and plot for the step function.
a pulse (dirac's delta).
The unit step function is also known as the Dirac delta function. It can be thought of as a function of the real line (x-axis) which is zero everywhere except at the origin (x=0) where the function is infinite in such a way that it's total integral is 1 - hence the use of the word 'unit'. The function is not a strict function by definition in that any function with the properties as stated (0 everywhere except the origin which by definition has a limit tending to 0), must therefore also have an integral of 0. The answer is therefore zero everywhere except at the origin where it is infinite.
Seventeen tens written in unit form is 170. This is because each "ten" represents a value of 10, so 17 tens equals 17 multiplied by 10, which is 170.

Below code generates unit step function n1=-4; n2=5; n0=0; [y,n]=stepseq(n0,n1,n2); stem(n,y); xlabel('n') ylabel('amplitude'); title('unit step'); It results in a unit step whose value is 1 for time T>0.
YES, unit step function is periodic because its power is finite that is 1/2.. and having infinite energy.

u(t)-u(-t)=sgn(t)
When the numerical value of a quantity is equal to the unit of that quantity, it means that the quantity being measured is equal to 1 in that unit. This often simplifies calculations and conversions in physics and mathematics.
Theta can take units of radians or degrees. However, the sine function itself does not have units. It returns a unit-less value.
Both pulse and impulse are the types of unit step function. In case of impulse the response gains the value for short duration of time and then becomes 0 while in case of pulse it is not neccessary that the value of response become 0 after an interval it may remain constant also.............
