had proposed a cosine basis neural network architecture for the design of Farrow structure based VBFs with the help of back-propagation based supervised learning algorithm. Haridas and Elias had proposed an efficient bank of filters for audiogram matching in a digital hearing aid which has derived from variable bandwidth filter (VBF) structure with the help of Farrow structure in order to achieve lower arithmetic complexity. Another technique had been developed for the construction of tuneable bandwidth linear phase FIR filters with the aid of different polynomials such as shifted Chebyshev polynomials, Bernstein polynomials and shifted Legendre polynomials. To achieve reconfigurability and low complexity in emerging communication applications, an efficient implementation of FIR filter with the aid of VBW and fractional delay is investigated in where the reduction in implementation complexity is achieved by converting the continuous filter coefficients to signed powers of two space. The study also extended their proposal by incorporating a novel structure for band-pass and band-stop filters with the feature of having not only adjustable upper and lower band edges but also with a lower arithmetic complexity. In, authors had introduced linear phase FIR filters that have adjustable bandwidth characteristics with a fixed phase response. To this aim, George and Elias had presented a continuous VBW sharp finite impulse response (FIR) filter designed with low complexity and minimum distortion. In connection to the design of VBW digital filters, Farrow structure has been widely used in most of the literatures. More specifically, design of hardware efficient variable bandwidth (VBW) digital filters had drawn sufficient attention which aims at utilising minimum hardware elements during its implementation and consume less amount of power. In connection with different types of digital filters existing in the literature, variable or tuneable bandwidth digital filters receive appreciable attention to the researchers due to its ever increasing demand for developing reconfigurable systems which are necessary in almost all field of applications such as digital audio, spectrum sharing radio, trans-multiplexers, sonar, radar, telecommunications, medical, spectrum analysis and so on. As a result, design of such type of systems has been broadly studied throughout the globe over the past few decades.

The 3 m whip can be configured for NVIS operation using the tie down kit included and can also be extended to 7 m with the 3 section Extension and Guy Kit for semi-permanent stationary use. The 3046 is offered with a 3 m carbon fiber MIL spec whip antenna, MIL spec rubber spring and NATO hole pattern base also with a compatible vehicle mounting bracket optional accessory. These features combine to provide an easy-to-use, trouble-free, high performance mobile antenna solution. The 3046’s innovative circuit design ensures power delivery to the antenna is maximised, and receive mode performance is optimised by the internal receive mode amplifier. The tuner has an unlimited tune from memory capacity, and using a state-of-the-art tuning algorithm, new frequencies are tuned in typically less than one second. With up to 150 W RF power handling capability, the 3046 can be used for voice (including frequency hopping) and data operation over the full 2 to 30 MHz frequency band.
