What is the difference between pulse signals and frequency signals?
Thread Content
Could some expert please explain the difference between pulse signals and frequency signals? What are the similarities and differences between them?
Personal understanding: Pulse signals correspond to cumulative amounts; a pulse is generated when a certain cumulative amount is reached, for example, 1 KG/PULSE. Frequency signals correspond to instantaneous values, and the frequency of the signal generated depends on the instantaneous value. This is somewhat similar to the common 4-20mA standard; for instance, 1 KG/H equals 1000 Hz. Of course, in most cases there is no fundamental difference between the two, and they can be converted into one another when used to represent cumulative amounts.
Essentially, there’s no difference – it’s all about high and low levels – but the way it’s expressed differs. Frequency refers to the number of high/low levels per second, hence the unit is “HZ”, while pulses are independent of time and are counted in units of “individuals”; this is just my personal understanding
The explanation was very detailed; thank you, sir!
A pulse signal is a type of frequency signal, but not all frequency signals are pulse signals.
The number of pulses detected per unit time is the frequency.
It’s just a matter of different units; that’s what I think
