father‚ Alois initially bore his mother’s surname‚ Schicklgruber. In 1842‚ Johann Georg Hiedler married Alois’s mother‚ Maria Anna. After she died in 1847 and Johann Georg Hiedler in 1856‚ Alois was brought up in the family of Hiedler’s brother‚ Johann Nepomuk Hiedler.[3] In 1876‚ Alois was legitimated and the baptismal register changed by a priest to register Johann Georg Hiedler as Alois’s father (recorded as Georg Hitler).[4][5] Alois then assumed the surname Hitler‚[5] also spelled as Hiedler

LNA Design Iulian Rosu‚ YO3DAC / VA3IUL http://www.qsl.net/va3iul/ An LNA combines a low noise figure‚ reasonable gain‚ and stability without oscillation over entire useful frequency range. The Low Noise Amplifier (LNA) always operates in Class A‚ typically at 15-20% of its maximum useful current. Class A is characterized by a bias point more or less at the center of maximum current and voltage capability of the device used‚ and by RF current and voltages that are sufficiently small relative

and the related components amplify the sound signals picked up by the condenser microphone (MIC). The amplified signal from the preamplifier stage is fed to input pin 3 of IC LM386N (IC1) through capacitor C2 (100nF) and volume control VR1 (10-kilo-ohm log). A decoupling network comprising resistor R5 and capacitor C3 provides the preamplifier block with a clean supply voltage. Audio amplifier IC LM386N (IC1) is designed for operation with power supplies in the 4-15V DC range. Circuit diagram:

Such included the number of children within the von Trapp family from actually being 10 children and not seven and even the sexes‚ ages and names were altered. She also did not fall in love with Georg von Trapp but instead the children. When the time came for her to marry him she became very unsure of whether or not she could simply discard her religious calling. They also wedded in 1927‚ being eleven years before the von Trapp family was forced

All types of Motor & Generators - AC & DC‚ Starters:Induction Motor (3 Phase):The production of a rotating magnetic field (RMF) is essential for the operation of alternating current (a.c.) induction motors. The speed of rotation of an RMF is known as the synchronous speed and this will be governed by the value of the supply frequency and the number of poles wound within each phase winding. Each of the phase windings are 120 electrical degrees apart. Synchronous speed can be calculated using the following
