In this paper, a method of realizing voltage-mode (VM) non-inverting high-pass filter (HPF), band-pass (BPF), low-pass (LPF), and inverting (ILPF) transfer functions structure with two grounded capacitors four resistors through an analytical synthesis is presented. The the VM biquadratic consists voltage proportional block lossless integrators based on use current feedback operational amplifier...

Pass-transistor switch networks have many advantages over gate-level networks, incZuding high density, high speed and low power dissipation. However, their design and analysis lack rigorous mathematicaZ tools. This paper studies the appZication of the multiple-vaZued switch-ZeveZ algebra introduced in 131 to the design and analysis of passtransistor networks. After briefly introducing this mult...

The problem of the realization of integral sliding mode controllers based only on output information is discussed. The implementation of an output integral sliding mode controller ensures insensitivity of the state trajectory with respect to the matched uncertainties from the initial time moment. In the case when the number of inputs is more than or equal to the number of outputs, the closed lo...

This work is devoted to study the existence of solutions to equations of the p-Laplacian type in unbounded domains. We prove the existence of at least one solution, and under further assumptions, the existence of in nitely many solutions. We apply the mountain pass theorem in weighted Sobolev spaces.

This paper studies the existence of multiple solutions of the second-order difference boundary value problem Δ2u n − 1 V ′ u n 0, n ∈ Z 1, T , u 0 0 u T 1 . By applying Morse theory, critical groups, and the mountain pass theorem, we prove that the previous equation has at least three nontrivial solutions when the problem is resonant at the eigenvalue λk k ≥ 2 of linear difference problem Δ2u n...

A channel delay can be estimated by evaluating the channel response to a deterministic signal. In the frequency domain, a maximum likelihood delay estimator which accounts for colored Gaussian measurement noise can be formulated. A procedure that allows fast estimation of the channel delay is proposed, in case a low-pass deterministic signal is applied to the channel. Keywords—Fractional delay;...
