Spoken Grammar: Vague Language and EAPll become especially interesting when the analog front-end is implemented together with the digital part. The first monolithic CMOS RF transmitter has been presented in [Rof98]. The transmitter is part of a complete low-power transceiver operating in the 902-928 MHz ISM frequency band, which is one

Intonational Meaning Starting from Talkhe quadrature direct digital synthesizer (QDDS), and .)> .) are pulse shaped and interpolated quadrature data symbols [Tan95a]. In the base station, the multi-user I/Q data is combined and weighted and so the input of the I/Q branches is 12 bits in Table 12.1. The specifications are not so strict in

Spoken Language Generation and Understandingscribes an architecture where a multi-carrier GMSK modulated IF signal is up converted to RF by two mixers and bandpass filters (BPFs) as shown in Figure 13.1. This saves a huge number of analog components, many of which require production tuning. Consequently, an expensive and tedious part of the m

Splunk Search Processing LanguageIn this chapter the operation of the direct digital synthesizer is first described. It is simple to add modulation capabilities to the DDS, because the DDS is a digital signal processing device. It is shown that the DDS produces spurs as well as the desired output frequency.
