ABSTRACT:
A voltage divider circuit having divider resistors which are not precision resistors. A first oscillating signal is input into a first resistor and the complement of the first oscillating signal is input into a second resistor. The two resistors are connected together and to a filter. Other means, such as transistors, may be utilized in lieu of the resistors. The output at the filter is the D.C. level of the first oscillating signal which is one-half or other designated ratio of the input voltage. Buffers may be incorporated in the invention.
