A: using a multimeter or scope it can be verifies the states of a logic device either as '1' or a '0' which translates to true = hi [volts] = '1' and '0' as low [volts] = '0'. '0' is a false state and '1' is a true state. Must add that the voltmeter will not decipher hi or low if toggling

How do you check an inverter circuit?
An inverter logic device is characterized by an P-channel BJT Bipolar Junction Transistor internally. This simply means by applying an logic HIGH on input X will result in logic LOW on output Y. The Boolean expression for this device is X NOT Y . (XY') INPUT X | OUTPUT Y ---------------------------- 1 | 0 0 | 1 1 = HIGH +5 Vdc 0 = LOW +0 Vdc Testing: Simple Logic Probe connected to Vcc and Gnd
Why an open ttl gate behaves as a logic high input?
because TTL have a bias input setup to eliminate noise therefore the output will follow the logic one input if left open
What is propagation delay in flip flops?
Propagation Delay In digital logic, every gate has got some finite amount of delay because of which the change in the output is not instantaneous to the change in the input. In simple terms, the times it takes for an input to appear at the output is called the propagation delay. In Figure 6, tPHL, describes the time it takes for an input to cause the output to change from logic-level-high to logic-level-low. Similarly, tPLH, refers to the delay associated when an input change causes the output to change from logic-level-low to logic-level-high. The overall delay is average of these two delays.
Why diode logic gate is not suitable for cascading operation?
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
Why diode logic cannot perform a NOT function?
Diode logic cannot perform a NOT function because diodes only allow current to flow in one direction, which prevents them from creating a true inversion of the input signal. In a NOT gate, the output must be the opposite of the input; for instance, if the input is high (1), the output should be low (0), and vice versa. However, in diode logic, when the input is high, the diode conducts, leading to an output that is also high, failing to achieve the desired inversion. Thus, diode logic is limited to implementing basic AND and OR functions but cannot produce a NOT operation.
Answer What is the difference between output and input?
Input devices help in input to a device and output devices handles the output to be fed to another device. For example an input device should have high impedance so that it should not load the output device to which it is connected. Also it should condition the input so that it can be acceptable to the device to which it is fed. Output devices normally help in the device to which they are connected to have low impedance so that they can offer more output and have a smooth functioning. The keyboard is an input device and the monitor, printer etc are output devices. You behave like a teacher in your question like asking others to give a drawing and mention parts. It will take more time and I cannot afford. ovipapi@gmail.com
What is a TTL-compatible output?
Compatibility in TTL means that the output of one TTL device can be used to drive the Input of the other TTL device , This because the low and high output window fit inside the low and high input window/profile TTL stand for Transistor Transistor Logic, so any voltage between 0 and 5 volt is compatible where any voltage between 3V and 5V is logic 1 and zero volt is logic 0
What is a TTL compatible output?
A: TTL gates operates on the premise of having +5 dc on the rail therefore the output will be in the range +5 volts. A cmos gate while similar to a TTL function is not really compatible since the output volts can be 12 volts or more. Besides that TTL gates require some input current for it to operate
What does high input means in decoder?
In the context of a decoder, "high input" typically refers to an input signal that is at a logic high level, representing a binary value of '1'. When the decoder receives a high input on one of its lines, it activates the corresponding output line, effectively translating the binary input into a specific output. This is crucial for applications like digital circuits where specific signals need to be routed based on the input conditions. High inputs are essential for determining which output should be activated in a multi-line system.
Output of logic gate is 1 all input are logic 0 the gate is?
If the output of a logic gate is 1 while all inputs are logic 0, the gate is a NOR gate. A NOR gate produces a high output (1) only when all its inputs are low (0). In contrast, other gates like AND, OR, and NAND would not produce a 1 output under these conditions.
Which logic gate has output high if and only if all inputs are low?
NOR - has two or more inputsinverter - only has one input, so that input is all inputs
Can nand be inhibitted or disabled?
I suppose so. If a three input NAND is used as a two input device, the third input can be viewed as an inhibit input. Also some NAND devices can be "3 stated" where the output goes to a high impedance.
