The basic difference between latches and flip flop is that flip flop has enable signal(ie,clock signal).Flip flop change their output depending on the clock signal.But in case of latch,there is no clock signal.
race around condition:Toggling the output of JK flip flop more than once for a single clock input.This happens because the pulse width of the clock input is greater than the propagation delay of the flip flop.This can be overcome by using Master Slave JK flip flop.

for asyn.transmission data is kept b/w start & stop bits.so there must b start/stop bit to identify the bits that r being trasnferred.this is known as ‘DATAFRAMING’.the start/stop bits r pre-defined.(i.e high or low).

EBCDIC Stands for Extended Binary Coded Decimal Interchange Code.Itz 8 bit code.
ASCII is 7 bit code

but latches has gates (transperant signal)
flip flop edge sensitive latches level sensitive
Which range of signals is used for terrestrial transmission?
ANS: Normally it is used in Satellite Comunication
L-Band is 1-2GHz
S-Band is 2-4GHz
Latch: Clock will not be requires
FlipFlop: Clock is requires
Basically 2 Types of filters
1) Analog : Low,High,Band,Notch
2) Digital:FIR, IIR, Butterworth, Chebushev Filters
ans19-modulation is required to
1-practicability of antenna size
2-narrow banding
3-long distance transmission.
4-for effective &efficient radiation
