Yes, you can change the delay to 1.5 us for low frequencies. The delay is however a function of the frequency! The bandwidth where the delay will be 1.5 us "-3dB" may be 200 KHz only.

Is this feasible for creating a much larger delay of 1.5µs by altering the R/C values?

The formula's contain an error: It is easy to see that for low frequencies, the circuit is inverting. The transfer function lacks a minus sign.

Formula's also ignore the bandwidth limitation of the op-amp.

The circuit needs to be driven from 0 Ohm impedance. Perhaps the circuit is not so briljant an accurate as the text shows.

It is still nice.

Hi guys Can someone tell me how to make my time delay to be little bit longer

Hi if there is any one who can hook me up with a phase delay circuit combined with a heterodyne reciever to detect very weak fm signals

this is a nice circuit.

answer my questions....tnx

what is the relation of capacitance and resistance in a delay circuit?is there any effect in a delay cicuit?how does the delay occur?

hi is there someboby who can help me, im looking for a circuit to invert video signal from a receiver. il be using this for a thesis.. thanks! if u have please contact me at email add. "adb_x@yahoo.com"

oops... i meant H(s) = 1*exp(j*-2*arctan(wRC)) => phase = -2*arctan(wRC) = w*Td ......ok, its not constant, sorry for the screw up.

isn't the phase delay (=> time delay) constant for all frequencies? --> H(s) = sqrt((1+(RCs)^2)/1+(RCs)^2)*exp(arctan(-wRC)-arctan(wRC)) = 1*exp(-arctan(2wRC)) => phase = 2wRC =>Tdelay = 2RC.............Is this right?

All my friends

It can be used in microphone arrays? If u know any time delay circuits, plz advice to me.

best regard

I have a task where I have to introduce two delays Sin() and Cos() of a 5kHz signal. Does somebody know solution satisfy my need? Lahan

Can y'all speak english?

HI WE ARE LOOKING FOR A CIRCUT TO SOFT START 12 SOCKETS 240 VOLT 5AMP 4 SOCKETS 1 SEC 4 SOCKETS 1SEC 4 SOCKETS THANK YOU

I would be interested in other similar designs. william.kuipers@tiscali.nl Thanks.

am a new user

I'm looking for analog designers. I have alot of activity going on within my office and I'd love to try and tell you what is available. If you have an updated resume, please forward that onto my e-mail address - raqui3co@hotmail.com. I look forward to speaking with you.

Avtually the circuit is inverting!! Unless you use an inductor instead of the capacitor. Furthermore the circuits needs to be driven from 0 Ohm impedance requiring input buffering! It works well with video signals, but only for relatively small bandwidth/delay products. I use a higher order modified circuit with 1 AD8055 opamp and 90ns delay for 0 to 7 MHz with one inductor and two capacitors.

i am a new members so i want to get free design of delay time circuit, because i want to make moving sensor using infra red with delay time. Thank's

in every frequncy the ampedanc of RC chang and your time delay will be chang whith frequncy.

nice, simple, useful.

thank you for this circute . but in every frequncy the ampedanc of RC chang and your time delay will be chang whith frequncy.I know very good method to creating a fixed time delay for all frequency. my chat ID : vartan_sah@yahoo.com

The product catalogues are still needed.

I have a question about this circuit. What is the response of this circuit when the input signal is a video signal? We know that RC resistance will change for different frequencies.
