Radio data charts: A series of forty-three abacs providing most of the essential data required in receiver design

Description

This book has a vertical format, the spine at the top, and pages turning like a flip-chart; printing on the outside covers follows this pattern. The contents consist of 43 charts arranged by number as follows: 1. Frequency and wavelength; 2-6: Inductance: Capacity, and Frequency: Short Wave, Medium Wave, Long Wave, IF Range, Audio Range; 7-9: Self-inductance of: Single-layer Solenoids 0.2-20 Microhenrys, Single-layer Solenoids 20-10,000 Microhenrys, Multi-layer Coils of Circular Section; 10-13: Diameter of Wire or Strand to Give Coil of Minimum RF Resistance; 14: Approximate RF Resistance of Coil when Wire Diameter is Optimum; 15: Ratio of RF Resistance to DC Resistance of a Coil; 16: Change of Inductance of Coil due to a Co-axial Cylindrical Screening Can; 17: Increase of RF Resistance of Coil due to a Co-axial Copper Screening Can; 18: Dynamic Resistance of a Parallel Tuned Circuit; 19: Universal Selectivity Chart; 20: Coupling Coefficient of IF Transformers; 21: Reactance of Coil or Condenser at Radio Frequencies; 22: Reactance of Coil or Condenser at Audio Frequencies; 23: Characteristic Impedance of Transmission Lines; 24: Attenuation of Two-wire and Co-axial Transmission Lines; 25: “Q” of a Quarter-wavelength Copper Resonant Line; 26: Resonant Impedance of a Quarter-wavelength Transmission Line; 27: Length of a Capacity-loaded Quarter-wavelength Transmission Line; 28-31: Mains Transformers: Turns per Volt, Wire Diameter and Winding area, Copper Loss, Iron Loss at 50 c/s; 32: Turns Ratio of Output Transformer; 33: Design of Chokes and Transformers Carrying AC Only at 50 c/s; 34: Design of Gapped Iron-cored Chokes and Transformers Carrying DC; 35: Design of Gapped Iron-cored Chokes: Determination of the Optimum Gap; 36: Comparative Efficiency of Gapped and Ungapped Chokes and Transformers Carrying DC; 37: Gain of Resistance-coupled Amplifiers; 38: Transmission and Phase Shift of RC Couplings; 39: Loudspeaker Dividing Network; 40: Decibels up and Down; 41: DC Resistance of Wire; 42: Universal Resistance Chart; 43: Attenuation Circuits of Constant Resistance; Copper Wire Tables.
