An equivalent baseband signal or equivalent lowpass signal is a complex valued representation of the modulated physical signal (the so-called passband signal or RF signal). It is a concept within analog and digital modulation methods for (passband) signals with constant or varying carrier frequency (for example ASK, PSK QAM, and FSK).
At the end of 2015, the ATIV Book 9 Pro and Book 9 Spin were introduced [26] (also known as Samsung Notebook 9 in some regions), [27] [28] [29] both running on an Intel Core i7 processor. The Notebook 9 Pro features a 4K resolution display, while the Notebook 9 Spin is a 360-degree convertible. [30] Then at CES 2016, the Samsung Notebook 9 was ...
It may refer more specifically to two subcategories: Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum. Baseband bandwidth is equal to the upper cutoff frequency of a low-pass filter or baseband signal, which includes a zero ...
The passband of a receiver is the range of frequencies it can receive when it is tuned into the desired frequency (channel). A bandpass-filtered signal (that is, a signal with energy only in a passband), is known as a bandpass signal, in contrast to a baseband signal. [1] The bandpass filter usually has two band-stop filters.
The resulting so called equivalent lowpass signal or equivalent baseband signal is a complex-valued representation of the real-valued modulated physical signal (the so-called passband signal or RF signal). These are the general steps used by the modulator to transmit data:
Samsung Notebook, formerly known as Samsung Sens (삼성 센스), also marketed as Samsung Notebook Series (2011–2013), is a line of portable computers produced by Samsung Electronics. The Sens line was first launched in 1995 and lasted until 2013, exported overseas without the Sens branding, and replaced by Samsung Ativ .
According to the most common definition of a digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion.
Samsung Galaxy Book is a line of Microsoft Windows based laptop computers produced by Samsung Electronics of South Korea. The Galaxy Book originated as tablet computers with detachable keyboards, however in 2020 it had evolved into becoming Samsung's main line of laptops, replacing the Samsung Notebook .
