When extremely critical timing is required, a quartz crystal can be used.
Does the 74123 one shot have an internal timing resistor?
In a typical IC monostable multivibrator circuit, at the falling edge of the trigger input, the output switches HIGH for a period of time determined by the ________.
With most monostable multivibrators, what is the Q output when no input trigger has occurred?
The monostable multivibrator circuit is not an oscillator because ________.
To obtain a 50% duty cycle in an astable 555 timer circuit:
When a capacitor charges:
When the 74123, a retriggerable monostable multivibrator device, ends its timing cycle it must be started all over again.
In the 74121, which is nonretriggerable, any triggers that come in before the end of the timing cycle are ignored.
A monostable 555 timer has the following number of stable states:
An astable multivibrator requires:
A retriggerable one shot has a pulse of 10 ms. 3 ms after being triggered, another trigger pulse is applied. The resulting output pulse will be ________ ms.
What is another name for a bistable multivibrator?
The ________ is defined as the time the output is active divided by the total period of the output signal.
Timing accuracy of more than eight significant digits can be easily achieved by using quartz crystals.
A comparator simply outputs a HIGH or LOW based on a comparison of the voltage levels at its input.
A crystal demonstrates the ________ effect when a mechanical force across the crystal causes a small voltage to be generated.
