This is a graph of frequency response. The vertical axis is marked off in dB from 4 to 16 with marks every dB. The horizontal axis is in cycles on a logarithmic scale from 1 cycle to 1 megacycle. The graph line starts out at 5 dB at 1 cycle. It rises smoothly to almost 12 dB at 10 cycles. At about 25 cycles it begins a rise to a smoothly rounded peak at about 225 cycles. After the peak it falls again to 11.75 dB at 1000 cycles and finally flattening out at 10.2 dB at 6,000 cycles. The curve continues flat until 100 kc at which point it begins to fall off reaching 5 dB at 1 Mc. End verbal discription.
