Answer Posted / raveesh83
If we use the SSB technique and transmit picture
signal,then some portion of the other side band is also
transmitted. This is due to the transition band of the
actual filter which is quite large. If the cut off freq is
1000Hz with a transition band of 2.5% , then 1250Hz is
passes through that band. This is utilized in transmission
of picture signals.

interface an 8-pin switch with 8085 microprocessor located at 0AAH and LEDs at port 55H, draw the circuit diagram. Write down a program to read the switches and do the following: > if the parity of the switch is odd, start counting upward until it reaches 0FFH. > if the parity of the switch is even, start counting downwards until it reaches 00H.
