How do you find the time delay between two signals?

τdelay=argmax ((f∗g)(t)), this will estimate the time offset where the signals are best aligned.

What is delay time estimation?

Time delay estimation (TDE) is the problem of estimating the time delay between two received signals which have originated from same transmitter. ¹. This estimation problem is of fundamental importance in radar signal processing for detecting the presence of targets and identifying radar transmitters.

How do you calculate time delay between two signals in Matlab?

d = finddelay( x , y ) returns an estimate of the delay d between input signals x and y . Delays in x and y can be introduced by prepending zeros. d = finddelay( x , y , maxlag ) uses maxlag to find the estimated delay(s) between x and y .

How do you calculate filter delay?

The formula is simple: given a FIR filter which has N taps, the delay is: (N – 1) / (2 * Fs), where Fs is the sampling frequency. So, for example, a 21 tap linear-phase FIR filter operating at a 1 kHz rate has delay: (21 – 1) / (2 * 1 kHz)=10 milliseconds.
