How long can the INTR signal stay high?
The INTR pulse can remain high until the interrupt flip-flop is set by the EI instruction in the service routine. If it remains high after the execution of the EI instruction, the processor will be interrupted again, as if it were a new interrupt.
What is the minimum number of samples that pulse amplitude modulation needs to take per second to reproduce this signal accurately?
Fs=2Fm
Why colour burst required in TV?
The 8 cycle color burst pulse on the back porch of the horizontal retrace pulse of the NTSC signal is required in order to maintain phase lock synchronization between the transmitter's chroma modulator and the receiver's chroma demodulator.
What type of signal must be applied to the input of a microprocessor?
square pulse signal
Every pulse in a digital signal?
Bit
What type of modulation is pulse position modulation and why?
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
A digital signal composed of a pulse of positive voltage represents a what?
A pulse is just a pulse. Its meaning depends on context and the design of the system.
Is pulse wave an analog or digital signal?
Yes, it is
What digit represents a digital signal composed of a pulse of positive voltage?
A pulse is just a pulse. Its meaning depends on context and the design of the system.
How regenerative repeater work in pulse code modulation?
Regenerative Repeater is used for the PCM (Pulse code modulation ) it amplifies the signal because the effect of the channel over the signal .
What is pps signal?
A pps signal stands for pulse per second. It is electric and repeats one every second. Pulse per second is mostly involved in health care; for example, nursing.
