  2. Equivalent input - Wikipedia

    en.wikipedia.org/wiki/Equivalent_input

    Equivalent input (also input-referred, referred-to-input (RTI), or input-related), is a method of referring to the signal or noise level at the output of a system as if it were due to an input to the same system. This input's value is called the Equivalent input.

  3. Response to Intervention - Wikipedia

    en.wikipedia.org/wiki/Response_to_Intervention

    The RTI process within MTSS can help to identify students who are at-risk, inform any adjustments needed to the instruction, monitor students' progress, and inform other necessary interventions.v There are at least four main reasons for implementing RTI to address the academic needs of students: [9] To increase achievement for all students

  4. Carnegie Unit and Student Hour - Wikipedia

    en.wikipedia.org/wiki/Carnegie_Unit_and_Student_Hour

    The Student Hour is approximately 12 hours of class or contact time, approximately 1/10 of the Carnegie Unit (as explained below). As it is used today, a Student Hour is the equivalent of one hour (50 minutes) of lecture time for a single student per week over the course of a semester, usually 14 to 16 weeks.

  5. Effective input noise temperature - Wikipedia

    en.wikipedia.org/wiki/Effective_input_noise...

    In telecommunications, effective input noise temperature is the source noise temperature in a two-port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual network or amplifier connected to a noise-free source.

  6. Noise figure - Wikipedia

    en.wikipedia.org/wiki/Noise_figure

    where SNR i and SNR o are the input and output signal-to-noise ratios respectively. The SNR quantities are unitless power ratios. Note that this specific definition is only valid for an input signal of which the noise is N i =kT 0 B. The noise figure NF is defined as the noise factor in units of decibels (dB):

    The North American College and Community Radio Chart, often abbreviated as NACC, is a weekly Top 200 radio chart launched in January 2017. [1] As of 2018, the NACC chart receives weekly airplay reports from over 200 radio stations across North America. [2] [3]

  8. Academic grading in the United States - Wikipedia

    en.wikipedia.org/wiki/Academic_grading_in_the...

    A-plusses, if given, are usually assigned a value of 4.0 (equivalent to an A) due to the common assumption that a 4.00 is the best possible grade-point average, although 4.33 is awarded at some institutions. In some places, .25 or .3 instead of .33 is added for a plus grade and subtracted for a minus grade.

  9. HIPO model - Wikipedia

    en.wikipedia.org/wiki/HIPO_model

    HIPO model (hierarchical input process output model) is a systems analysis design aid and documentation technique from the 1970s, [1] used for representing the modules of a system as a hierarchy and for documenting each module.
