In 8085 processor TRAP is a non maskable interrupt.Whereas RST 7.5,6.5,5.5, intr are maskable interrupts.
Maskable means this interrupts can be left without considering during the execution of the pr...
When logic signal is applied to a maskable interrupt input,the 8085 is interrupted only if that particular input is enable.These interrupts can be enabledisabled under program control.
Amplitude modulation: the encoding of the carrier wave by variations of its amplitude in accordance with an input signal.
A broadcast system that uses amplitude modulation.
noise in modulation: noise produced by undesirable amplitude variations of radio-frequency signal.
