CurvFit: a curve fitting program with Lorentzian, Sine, Exponential and Power series are available models to match your data. 
MatchnFreq: a Matched Filter program used to filter signals and slim pulses. 
Electrical Filter Design: find the transfer function's poles & zeros; H(s) = Y_{out}(s) / Y_{in}(s). Pulse Slimming to minimize InterSymbol Interference: via Arbitrary Equalization with Simple LC Structures to reduce errors. Voice Coil Motor: basically an electromagnetic transducer in which a coil placed in a magnetic pole gap experiences a force proportional to the current passing through the coil. 
AC Motor Design: a simulation program for A.C. motor design that was reapplied as a constrained optimization problem with 12 unknown parameters and 7 constraints. Digitized Signal from Magnetic Recording: Magnetic recording of transitions written onto a computer disc drive may produce an isolated pulse as shown. PharmacoKinetics: an opentwo compartment model with first order absorption into elimination from central compartment is presented here.
