Webb23 jan. 2024 · In his work he mainly focuses on the pentagrid {5,4} and heptagrid {7,3}:. In what ways are these tilings special? How do they compare to hyperbolic tilings in general?I am wondering what insights from these two cases are unique to these two cases, and what insights can transfer to all other possible tilings in the hyperbolic plane.

Webb13 feb. 2011 · The mixer diodes are shorted in pairs causing the IF signal to be flipped in polarity at the rate of the LO signal. This alternating polarity applied to the IF (or RF) creates the up/ down conversion. Therefore the LO signal must be strong enough to fully drive the diodes, ideally the LO signal is a square wave of current. Webb14 apr. 2024 · The pentagrid also featured in a UK patent (GB426802) granted on 10 April 1935. However, the Ferranti company of Great Britain entered the valve business with the first known UK-produced pentagrid, the VHT4 , late in 1933 (though it must have been in development, and would certainly have existed as a prototype well before that time).
