Amplitude Shift Keying (ASK) -Digital To Analog Conversion and Transmission Tutorials Part II

Amplitude Shift Keying (ASK)is implemented by changing the amplitude of a carrier signal to reflect amplitude levels in the digital signal. For example: a digital “1” could not affect the signal, whereas a digital “0” would, by making it zero. The line encoding will determine the values of the Analog waveform to reflect the digital…… Continue reading Amplitude Shift Keying (ASK) -Digital To Analog Conversion and Transmission Tutorials Part II

Phase Shift Keying (PSK) – Digital To Analog Conversion and Transmission Tutorials Part IV

Phase Shift Keying (PSK) – Basic Tutorials We vary the phase shift of the carrier signal to represent digital data. The bandwidth requirement, B is: B = (1+d)xS PSK is much more robust than ASK as it is not that vulnerable to noise, which changes amplitude of the signal. Binary phase shift keying(See Diagram Above)…… Continue reading Phase Shift Keying (PSK) – Digital To Analog Conversion and Transmission Tutorials Part IV

Semaphores-Computer Science Tutorial Programing Languages (Mutex Vs Semaphores )

In 1965, Edsger Dijkstra, a Dutch computer scientist, introduced the concept of a binary semaphore into modern programming to address possible race conditions in concurrent programs. His very simple idea was to use a pair of function calls to the operating system to indicate entering and leaving a critical region. This was achieved through the…… Continue reading Semaphores-Computer Science Tutorial Programing Languages (Mutex Vs Semaphores )
