    Comparison Of Methods For Impulse Response Computation
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Karsky, Vilem
    This paper deals with obtaining impulse responses from integer order and fractional ordertransfer functions. There are shown three method how to compute inverse Laplace transform. The firstmethod is based on Mittag-Leffler functions, the second method is formed on generalized Laguerrefunctions and the third method lays on Fourier transform. These methods are also compared on twoexamples.

    Derivation And Practical Comparison Of Recursive Ls And Tls System Identification Methods
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Friml, Dominik
    The least squares (LS) type of methods are the most widely used methods in system identificationdespite their obvious imperfection. Such methods use a regressor, that is supposed not tocontain any error, notwithstanding that it is constructed from measured data. This can be solved byusing the total least squares (TLS) type of methods. Derivation of both batch and recursive methodsof LS and TLS for identification and their practical comparison is presented in this paper

    Comparison Of Modern Video Codecs For 4k And 8k Video Content
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Budáč, Adam
    The purpose of this paper is to compare modern video codecs, that ensure delivery of 4Kand 8K video content in high quality at reasonable bitrates. There are compared three video codecs:HEVC, VVC and the AV1. Video quality assessment is ensured by using four objective video qualitymetrics, which are: PSNR, SSIM, VIF and VMAF. For tests, there were chosen two from total ofseven videosequencies with different parameters: very high resolutions, high framerates, wide rangeof spatial and temporal indexes and 3D and 360° projection.

    Smart Home Wired Architecture
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Sykora, Tomas
    This article deals with the problem of Smart home systems. Electrical installations innew built and older buildings have recently integrated smart devices. These devices use IoT technology,which needs to communicate with each other. This article discusses the possibilities of replacingmost often used wireless communication for a new type of wired based on Industry IoTstandards. Using wired technologies will enhance the system reliability, safety and security. Whatmore it involve reduction of the electromagnetic smog, a potentially health-endangering effect generatedby devices communicating wirelessly at high frequencies.

    Modeling Of Multiple Electrode System For Inhomogeneity Detection
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Mancl, Vlastimil
    Capacitive sensing gained on popularity through the last decades. From proximity sensorsthrough humidity measurement to touch screen matrices. Capacitive sensing offers reliability,simplicity, and low financial cost. One of the crucial parts of the capacity sensor is the setup of theelectrodes. The behavior of such setup is often needed to be known before application. Due to thecomplex nature of electrostatic arrays, the precise analytic solution is often unavailable so the othermeans to gain solution is needed. This paper focuses on using the simulation for modeling of multipleelectrode setup, which could be used for measuring inhomogeneity in an otherwise homogeneousdielectric. The paper describes the problem of sharp edges. The description of the sensing depth of aplanar capacitor is also included. Three simulations were created to prove initial assumptions.
