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 ...
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.
Digital marketing mix is fundamentally the same as Marketing Mix, which is an adaptation of Product, Price, Place and Promotion into digital marketing aspect. [48] Digital marketing can be commonly explained as 'Achieving marketing objectives through applying digital technologies'.
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.
It is believed that there is an optimal way of allocating budgets for the different elements within the promotional mix to achieve best marketing results, and the challenge for marketers is to find the right mix of them. Activities identified as elements of the promotional mix vary, but typically include the following:
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]
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 ...
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.
