This webinar by Mykhailo Popryaga was delivered at Embedded Community Webinar #4 on September 18, 2020. Webinar agenda: - the problem of building systems for measuring electrical signals in the frequency range from tens of hertz to units of megahertz - several interesting circuit solutions (lock-in amplifier, trans-impedance amplifier, low noise amplifier), which are widely used in scientific electronics - noise and interference problems and general stages of measuring system development More details and presentation: https://www.globallogic.com/ua/about/events/embedded-community-webinar-4/
