The 74190 is an up/down decade counter. Counters use frequency division to achieve a counting sequence. To answer your question, it depends on the input frequency. The Qa output will divide the clock input by 2 so if the input is 100Hz, Qa's output is 50Hz. Since this is a decade (0 to 9, or truncated sequence) counter and not a binary (0 to 15, or full sequence) counter, the outputs Qb, Qc and Qd divide the input but their outputs are not symmetrical (equal time high and time low). Qb and Qc produce 2 pulses for every 10 input pulses, therefore divide the input clock by 5. Qd produces one output pulse for every 10 input pulses, therefore divides the input by 10. The easiest way to visualize this is to write out the binary count in column format, starting at 0000 and ending at 1001, and looking at each of the output patterns. To produce the 50Hz output, assuming you are not concerned over symmetry: -input clock 100Hz for 50 Hz on Qa -input clock 250Hz for Qb or Qc output of 50Hz -input clock 500Hz for Qd output of 50Hz
is an omr and input or output device?

What is the difference between output and input?If you sing into a microphone you can hear the microphone's output.Sound coming out of the power amp to the speakers.That is the input of the loudspeaker.Do you see the difference?Your voice is the microphone's input. Its output is electrical impulses that are input to the amplifier. The amplified impulses are the output of the amplifier and input to the speaker. Sound waves are output of the speaker and input to your ears.
A microprocessor with its external memory, input/output interface devices, and buffer, clock, and driver circuits. Abbreviated MPU.
Output is always greater than input. The output is multiplied from input.
