Hi,I have few questions regarding the analog signal processing.How are analog signals processed using Step 7?How are analog input signals converted to digital input signals and digital output signals to analog output signals?What is the function of scali In analog-signal processing the need often arises for a circuit that takes two analog inputs and produces an output proportional to their product. Such circuits are termed analog multipliers. In the following sections we examine several analog multipliers that depend on the exponential transfer function of bipolar transistors An analog signal can only be read by an analog I/O, but a digital one can use both analog or digital I/Os. There is sometime a possibilities to convert an analog signal into a series of digital ones. Because, in practice, you never connect a digital signal to an analog I/O because the analog I/Os are way more expensive than digital ones

Systems are operators that accept a given signal (the input signal) and produce a new signal (the output signal). Of course, this is an abstraction of the processing of a signal Amplitude Modulation. Amplitude modulation is a process by which the wave signal is transmitted by modulating the amplitude of the signal. It is often called as AM and is commonly used in transmitting a piece of information through a radio carrier wave. Amplitude modulation is mostly used in the form of electronic communication

Modulation is the process of converting data into electrical signals optimized for transmission. Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method. Analog modulation is typically used for AM, FM radio, and short-wave broadcasting PWM stands for pulse width modulation, the length of the pulse specifies the servo output or throttle position, and therefore it shares characteristics of both digital and analog signals.
