Digital temperature effect generator |
摘要 |
A circuit for simulating the effects of a temperature change in a digital transmission medium. The circuit generates lengthened or shortened frequency pulses digitally by operating a pulse counter to reset early for a shortened pulse or skip a timing pulse for a lengthened interval pulse. A second counter and associated decoder are utilized to alternately control the operating modes.
