Commonly-Used Nomenclature
This manual uses the following general nomenclature:
• Matrix variables are generally denoted with capital letters; vectors are
represented in lowercase.
• G(s) is used to denote a transfer function of a system where s is the
Laplace variable. G(q) is used when both continuous and discrete
systems are allowed.
• H(s) is used to denote the frequency response, over some range of
frequencies of a system where s is the Laplace variable. H(q) is used to
indicate that the system can be continuous or discrete.
• A single apostrophe following a matrix variable, for example, x',
denotes the transpose of that variable. An asterisk following a matrix
variable (for example, A*) indicates the complex conjugate, or
Hermitian, transpose of that variable.
