If R1 equals 450Ω, 10x attenuation and 500Ω input resistance result. R1 of 4950Ω causes a 100x attenuation with 5k input resistance. The 50Ω line theoretically constitutes a distortioness transmission environment. The apparent simplicity seemingly permits 'do-it-yourself' construction but this section's remaining figures demonstrate a need for caution.
