signal

  1. C

    There is a nonsense signal about Convolution and I couldn't understand what to do.

    First of all, I wholeheartedly greet my colleagues and the entire community! I’ve set the signal as m(t) = −t [ u(t) − u(t−2) ] and the impulse response as h(t) = 2 [ u(t−3) − u(t−4) ]. But while trying to find y(t), I ran into a small issue with the sketches. Because there is no overlap, and...

    a strange question I have about signals and systems?

    i salute the whole community I came across these two while working on signals and systems, what does it mean? I mean, I couldn't figure it out in my head, how are they being used?

    Practical Audio Signal Generator for the Felephone Online and Free

    I often use an audio signal generator on my cell phone at work. The generator is online and no registration is required. It generates signals with different waveforms, such as triangle, square, sine, and sawtooth. The generated signal ranges from 1Hz to 20kHz.I use it often so I don't have to...
