Calculation of simple MU - electrode transfer functions (inner wrapper)

Description

Compute discrete, unnormalized values of the transfer function from the motor unit .MU to the electrode .electrode. For the transfer function model, see comments above.

Usage

simple.TF(.MU, .electrode, .kt)

Arguments

.MU	The motor unit which is the source of the surface potential.
.electrode	The electrode at which the potential is measured.
.kt	A vector containing the discrete angular frequencies at which the transfer function is to be evaluated.

Value

A list object providing two properties: First, a property '$sampled.data' containing the discrete values of the transfer function from motor unit .MU to electrode .electrode obtained by evaluation at the discrete angular frequencies kt. Values are _not_ normalized according to .dist.min. And second, a property '$amp' that contains the sum over all muscle fibers of the squared inverse of the distance from that fiber's innvervation zone to the electrode position. This will be used for normalization later on.
