Impulse Formula Impulse is a quantity that is closely related to momentum. Impulse is a vector, with both a value and a direction, and is represented by the symbol . Impulse is the product of a constant force , and a time interval . The Greek letter ("delta") is used to mean "the ...
Impulsein Physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object. It is represented by the symbol J and is usually expressed in Newton seconds or kg m/s.
. Theimpulse-momentum theoremstates that the impulse is equal to this change in momentum. Impulse is a vector, with both a value and a direction, and is represented by the symbol . Momentum is equal to the mass times the velocity of an object ( ). The unit of impulse is the Newton-s...
Momentum, denoted p, is shown in the diagram. Each sphere in the diagram has mass (m) and velocity (v) represented by vector symbols indicating that they have magnitude and direction. The larger sphere has more momentum even while the velocities are equal. ...
However, in DSP, a one-sample delay element is often represented as a box with a z−1 symbol. This comes from the mathematical properties of the z-transform, which we have not covered here in the interests of minimizing mathematics (although there is a discussion of z-transform in ...
In these methods, basis is used to match the major signal components, and a signal is represented by a weighted sum of a series of basis functions. Signal features are usually revealed via interpreting the physical meaning of variable parameters in the basis function, such as amplitude, phase,...

An FIR filter is built of multipliers and adders. A delay element, which is just a clocked register, is used between coefficients. A single delay element is represented with a D1D1 symbol. Figure below illustrates a 5-tap FIR filter. Taking into account the structure in Figure above, ...
and \(S(\upsilon )\) is the FT of the transmitted UWB pulse. This can be represented using Bessel functions as $$\begin{array}{rcl}Y(\upsilon ,\,f) & = & {a}_{v}S(\upsilon ){e}^{-j2\pi \upsilon {\tau }_{0}}\\ & & \times \,{\int }_{-\infty }^{+\infty }(\...
the value of the time-domain signal rsto be zero at that time point; otherwise, the noise blanker10sets the value of the time-domain signal rsaccording to the value of the time-domain signal r at that time point. The operation of the noise blanker10is represented as the following ...
