This paper presents a new design approach which generates high-order electrically tunable HF ICcompatible filters. The realized circuits are composed only from CMOS linear transconductance elements and grounded capacitors. ...

The paper adresses the problem of estimating the instantaneous frequency of discrete time sinusoids imbedded in Gaussian noise. The proposed method is based on a model of the signal phase as a polynomial. This approach ...

In a series of papers, [1]-[3], A. Câmpeanu and M. Naforniţă proposed a new active RC filter synthesis method based on mesh current emulation of LC ladder filter networks. Initially, the method was successfully applied to ...

The paper presents the characteristics of the parameters of the chirp signal, and the situations where this signal intervene. Using Kalman filtering, a few parameters of the chirp signal will be estimated, such as frequency ...
