Abstract:
A linear, continuous-time electrical signal processor having input-output characteristics as prescribed for a time varying signal input vector u(t) and a time-varying signal output vector y(t) specified for a state vector x(t) of state variables by equations{dot over (x)}=Ax+Bu andy=Cx+Du wherein A, B, C, and D are prescribed matrices,having a signal input means for the input vector u(t) and a signal output means for the output vector y(t), and being prescribed for a state vector w(t) of state variables by equations {dot over (w)}=Ã‚w+{circumflex over (B)}u andy=&Ccirc;w+Du whereinÃ‚={dot over (G)}Gâˆ’1+GAGâˆ’1, {circumflex over (B)}=GB and&Ccirc;=CGâˆ’1 with G(t) being preselected such that the state vector is w(t) is companded as compared with the state vector x(t).
