  2. Frequency-resolved optical gating - Wikipedia

    en.wikipedia.org/wiki/Frequency-resolved_optical...

    Frequency-resolved optical gating (FROG) is a general method for measuring the spectral phase of ultrashort laser pulses, which range from subfemtosecond to about a nanosecond in length. Invented in 1991 by Rick Trebino and Daniel J. Kane, FROG was the first technique to solve this problem, which is difficult because, ordinarily, to measure an ...

  3. Double-blind frequency-resolved optical gating - Wikipedia

    en.wikipedia.org/wiki/Double-blind_frequency...

    Double-blind frequency-resolved optical gating (double-blind FROG) is a method for simultaneously measuring two unknown ultrashort laser pulses. Well established ultrafast measurement techniques such as frequency-resolved optical gating and its simplified version GRENOUILLE can only measure one unknown ultrashort laser pulse at a time.

  4. Marketing mix modeling - Wikipedia

    en.wikipedia.org/wiki/Marketing_mix_modeling

    Marketing mix modeling (MMM) is an analytical approach that uses historic information to quantify impact of marketing activities on sales. Example information that can be used are syndicated point-of-sale data (aggregated collection of product retail sales activity across a chosen set of parameters, like category of product or geographic market) and companies’ internal data.

  5. Gating signal - Wikipedia

    en.wikipedia.org/wiki/Gating_signal

    The gating signal can be generated by various means, such as an external trigger, a specific voltage level, or a specific frequency range. Signal gating is often employed in applications where precise control over the transmission of signals is required. Here are a few examples of how signal gating is used in different fields: 1.

    en.wikipedia.org/wiki/Marketing_communications

    Marketing mix is the most important part of marketing strategy, which is "the framework to manage marketing and incorporate it within a business context [6] ". Marketing strategy: how a business achieves its marketing objectives. The initial step to achieve a marketing strategy is to identify the market target and build up a business plan. [6]

  7. Frequency (marketing) - Wikipedia

    en.wikipedia.org/wiki/Frequency_(marketing)

    In marketing and advertising, frequency refers to the number of times a target audience is exposed to a particular message or advertisement within a given time frame. [1] This concept is a fundamental element of marketing communication strategies, aiming to enhance brand recall, create awareness, and influence consumer behavior through repeated ...

  8. RFM (market research) - Wikipedia

    en.wikipedia.org/wiki/RFM_(market_research)

    RFM-I – Recency, Frequency, Monetary Value – Interactions is a version of RFM framework modified to account for recency and frequency of marketing interactions with the client (e.g. to control for possible deterring effects of very frequent advertising engagements).

  9. Spread spectrum - Wikipedia

    en.wikipedia.org/wiki/Spread_spectrum

    Techniques known since the 1940s and used in military communication systems since the 1950s "spread" a radio signal over a wide frequency range several magnitudes higher than minimum requirement. The core principle of spread spectrum is the use of noise-like carrier waves, and, as the name implies, bandwidths much wider than that required for ...
