  • Aliasing of the Schumann resonance background signal by sprite-associated Q-bursts 

    Guha, Anirban; Williams, Earle R.; Boldi, Robert; Satori, Gabriella; Nagy, Tamás; Bór, József; Montañá Puig, Juan; Ortega, Pascal (2017-12)
    Article
    Open Access
    The Earth's naturally occurring Schumann resonances (SR) are composed of a quasi-continuous background component and a larger-amplitude, short-duration transient component, otherwise called ‘Q-burst’ (Ogawa et al., 1967). ...
  • A novel method to determine the discharge coefficient of constant section nozzles under compressible dynamic flow conditions

    Restricted access - publisher's policy
    The present paper introduces a novel transient experimental method employed to determine the discharge coefficient of constant section nozzles of small diameters of 1 to 3 mm and with a length/diameter ratio of around one. ...
  • On the common mode response of fully differential circuits 

    Gasulla Forner, Manuel; Casas Piedrafita, Óscar; Pallàs Areny, Ramon (Institute of Electrical and Electronics Engineers, 2000)
    Conference report
    Open Access
    Differential circuits are often described by their differential gain and common mode rejection ratio (CMRR). This approach, however, neglects the effect that the common mode signal has on the transient response and stability ...
