Level Trigger:
1) The input signal is sampled when the clock signal is either HIGH or LOW.
2) It is sensitive to Glitches.
Example: Latch.
Edge Trigger:
1) The input signal is sampled at the RISING EDGE or FALLING EDGE of the clock signal.
2) It is not-sensitive to Glitches.
Example: Flipflop.
Level triggering means the specified action occurs based on the steady state value of the input. An SR flip flop is an example of this - so long as S is true, the flip flop will stay set.
Edge triggering, on the other hand, means the specified action occurs on the edge of the transistion of the input, either from low to high or from high to low. The clock input of a D flip flop is an example of this - once the event ocurrs, the input must go back to its prior state and then generate the triggering edge again.
ANSWER: level triggering means when a certain level is reached the output will change states .
ANSWER: Edge triggering means that the output will change state on a leading or falling input transition depending on the application. It has nothing to do with RS or set or reset if conditions are right.
Give the advantages and disadvantages of level-triggered over edge-triggered devices.
Disadvances of level triggered
If the shift register is synchronized (uses clock) the control signal is level triggered. If the shift register is asycronized (no clock) the control signal is edge triggered.
Manner in which a flip-flopis activated by a signal transition.It may be either +ve or -ve edge triggered fliop-flop.
disadvantage: concentrated stress on tip results in increased wear, in turn the follower becomes less accurate over time
flip flop:-> it work's on the basis of clock pulses.-> it is a edge trigerred , it mean that the output and the next state input changes when there is a change in clock pulse whether it may a +ve or -ve clock pulse.latch;-> it is based on enable function input-> it is a level trigerred , it mean that the output of present state and input of the next state depends on the level that is binary input 1 or 0.Both the flip-flop and latch are Sequential circuits....Flip flops are edge-triggered devices whereas latches are level triggered devices.latch does not have clock signal whereas flip flop does.Flip flop has two values while latch has only one value.A: A flip-flop can be set reset and pass date with a clock a latch is a two state switch of or onA flip flop will follow a clock a latch will remain status quo until it is unlatch. basically one does not use flip flop for latches and viceversa. both can be flip and latched by signals.
A D latch is level triggered. It will follow the input as long as the gate is true. Once the gate goes false, the output will stay at the last known value. A D flip flop is edge triggered. The output will not change until the edge of the gate. At that point, the output will go to the state of input, and then it will stay at that value.
Flip flop is edge triggered device
If the shift register is synchronized (uses clock) the control signal is level triggered. If the shift register is asycronized (no clock) the control signal is edge triggered.
in the case of edge trigger, it may generate unwanted interrupt when input signal has glitch and so on. on the other hand if edge trigger not seen in some special situation (eg. when process in the service routin) level trigger preffered!
in level trigger mode, the input signal is sampled when the clock signal is either high or low whereas in edge trigger mode the input signal is sampled at rising or at the falling edge. lever triggering is sensitive to glitches whereas edge trigger is non sensitive.. example: latch for level trigger and flip-flop for edge trigger
Because that is the definition of a latch. A J-K flipflop is master-slave triggered because that is the definition of a J-K flipflop. A D flipflop is edge triggered because that is the definition of a D flipflop.
An edge-triggered flip-flop changes states either at the positive edge (rising edge) or at the negative edge (falling edge) of the clock pulse on the control input.

a group of flip-flops sensitive to pulse duration is called latch whereas a group of flip-flops sensitive to pulse transition is called a register.
INTR, RST5.5, RST6.5, RST7.5, and TRAP are external interrupts in the 8085. INTR is the original style used in the 8080. It uses an INTA response and the external hardware is expected to provide an instruction to execute, typically a CALL or an RST. RST5.5, RST6.5, and RST7.5 are non-INTA interrupts, where there is no expected response for acknowledgement. RST5.5 and RST6.5 are level triggered, and RST7.5 is edge triggered. TRAP is similar to the RST interrupts in that there is no acknowledge sequence. It is both edge and level triggered. Further, it is non-maskable.
disadvantage: concentrated stress on tip results in increased wear, in turn the follower becomes less accurate over time
An SR flip-flop can be converted into an edge triggered flip-flop with preset and clear inputs by adding the clock and the asynchronous inputs.
