The purpose of this capillary, that does not contain the stationary phase, is to provide a pressure resistance to the modulator channel flow.
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. For example, the modulation signal might be an … See more In analog modulation, the modulation is applied continuously in response to the analog information signal. Common analog modulation techniques include: • Amplitude modulation (AM) (here the amplitude of the … See more Pulse modulation schemes aim at transferring a narrowband analog signal over an analog baseband channel as a two-level signal by modulating a pulse wave.
