Generation of ASK: Amplitude shift keying - ASK - in the context of digital communication is a modulation process which imparts to a sinusoid two or more discrete amplitude levels 1. These are related to the number of levels adopted by the digital message. For a binary message sequence, there are two levels one of which is typically zero. Thus the modulated waveform consists of bursts of a sinusoid. Demodulation of ASK: ASK signal has a well defined envelope. Thus it is amenable to demodulation by an envelope detector. Some sort of decision-making circuitry is necessary for detecting the message. The signal, which is a binary sequence is recovered by using a correlator and decision making circuitry.

触发器，eda.在实际的数字系统中往往包含大量的存储单元，而且经常要求他们在同一时刻同步动作，为达到这个目的，在每个存储单元电路上引入一个时钟脉冲（CLK）作为控制信号，只有当CLK到来时电路才被“触发”而动作，并根据输入信号改变输出状态。把这种在时钟信号触发时才能动作的存储单元电路称为触发器(Triggers, eda. The actual digital systems often contain a large number of memory cells, and at the same time they often require synchronized action, to achieve this purpose, the introduction of a clock pulse (CLK) in each memory cell circuit as a control signal , the arrival of the circuit only when CLK was only trigger the operation and change the output state of the input signal. The memory cell circuit that can trigger actions when the clock signal is called a flip-flop)
