Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...

The latest in the ‘retro’ series from the famous British hi-fi name is an integrated amp with decidedly 1960s styling. But it has much more than just nostalgic appeal Quad products have never really ...

Most polysaccharides are obtained by simple extraction from the organism that produces them. Identification of the extracted polysaccharide and evaluation of its purity constitute a complex process ...

Abstract: A simple, efficient cathode-ray tube deflection circuit suitable for standard television horizontal sweep applications with excellent linearity has been developed. The circuit employs either ...

Abstract: This paper presents a new family of Class-AB operational transconductance amplifier (OTA) circuits based on single-stage topologies with non-linear current amplifiers. The proposed ...
