Direct Digital synthesis (DDS)
[1]The DDS is an electronic gadget through which frequencies are generated from a given based
timer. [2]There are various systems that use DDS technology such as oscillators, Google maps,
phones, radio receivers. Most of the DDS used are ROM based. [3]The DDS can synthesis at the
time of input a digitalized wave from unknown frequencies. These digitalized waves that are
formed are later converted by a converter to analog signals at a fixed time at the output of the
converter to convert digital waves to analog based signals. The DSS has different applications such
as transfer of message safety and provision of high level of switching speed of frequencies. [4]The
specific approach of these research will rely on the functions of the DDs as compared to other
systems and the limitations of DSS. For instance the noise produced at high level frequencies by the
DSS and find the solution to the challenge affecting the DSS [5].The study will investigate the
outcome expected at the end study after careful speculation and analysis of data and the
improvements to be made on the reduction of noise at high frequencies of the DSS.
Literature Review
DSS falls among the various technologies that have been introduced to enhance the process of
frequency synthesis, apart from DSS The technologies such as PLL [6] .Since DSS is digital in
nature its main role is to generate analog signals through a conversion process of using a converter.
Various studies have proved that as compared to other frequency synthesizers, [7]The DSS has
proved to consume less power to be cheap as compared to other techniques which are expensive and
inefficient do the frequency switching at a high speed and conducts accurate and high resolutions in
digital wave form change to analog signals. [8] According to researchers the DSS has been found to
be so useful when developing other methods of high frequency ramps and those driven by signal
generators. [9] The use of Shannon sampling theorem methods have proved that the sampling rate
must be large compared to twice of the given frequency. [10] Hence a sampling rate of 40 Hz is
required which isn’t viable with the required standard measures.
According to [11] describes that a DSS can use the digital processor to manipulate all frequencies,
amplitudes and phases. Before the DSS were used for military technology because of its resolution
of phases and rapidly hopping over various frequencies, [12]however they were power hungry

According to [11] describes that a DSS can use the digital processor to manipulate all frequencies,
amplitudes and phases. Before the DSS were used for military technology because of its resolution
of phases and rapidly hopping over various frequencies, [12]however they were power hungry
making them unreliable but due to the improved technology on circuits the PLL (phase-locked loop)
technology was introduced for generation of output frequencies in a consumer synthesized
applicable [13]. Research has also found out that the e radar that is FMCW PLL based needs a
reference signal along with a small amount of jitter in the aspect of frequency as well as phase. [14]
This needed signal is generated with the help of DDS which works at a clock frequency of around
1.6 GHz. However the precision level of clock is always guaranteed with the using of VHDL
implementation of a nature controlled algorithm.
The DSS have become very competitive in the market because, excellent performance and
functionality, [15]The DSS gadgets have been reduced to small sizes to simple microchips these as
widened the applications of the DSS, However The PLL has a high level techniques of higher
frequencies and the DAC (Digital to analog converter) has outputs that are being generated at a
low frequency. [16] However still the DSS techniques stand out because of its techniques which led
to a high resolution and accuracy and switching capabilities at high speeds signals. [17]
Research questions
1. What are other new frequency synthesis techniques that need to be introduced to solve the
impending failures of DSS technique?
2. What are the new changes to be made to the DSS to make it more efficiency in the future of
postmodern advancement of technology?
3. What are the mechanisms to introduce for a better efficiency of DSS technologies in future?
Rationale
The main significance of the study is to enable understand the purpose and the functionality of the
DSS techniques in relation to other techniques and their applications.
From the literature review we found out that most of the industries prefer the use of DSS because of
their high resolution and accuracy and minimal use of power. The equation shows the time that the
DSS can take convert a digital waveform to an analog signal which is the shortest time possible.
This shows how significant the DSS can be in high speedy frequencies.
