Figure 4 eh.17. There are two parts to this figure. In part eh there are two input terminals on the left. The lower input terminal goes to ground. The upper terminal goes through a capacitor labeled C 1 to the grid of a triode. The grid goes to ground through a resistor labeled R 2. The grid also goes through a resistor, R 1 to E b b. The plate of the triode goes to E b b. The cathode goes through a resistor, R k to ground. The cathode goes through a capacitor, C 2 to the upper output terminal. The lower output terminal is grounded. In part b the lower input terminal is grounded. The upper input terminal goes through a capacitor, C 1 to the grid of a triode. The plate of the triode goes to E b b. The cathode goes through a resistor, R k 1 then through another resistor, R k 2 to ground. The junction of R k 1 and R k 2 goes through another resistor, R 1 to the grid. The cathode goes through a capacitor, C 2 to the upper output terminal. The lower output terminal is grounded.
