# The 3dB bandwidth of utc pd

#1

dear supporter,
when I do the transient simulation of utc pd, from the script, I get the time response and frequency response，the result as follows, .

1. the impulse response (the blue curve) that I feel is not correct;
2. the 3dB bandwidth is too large.
the model and scrip as follows,3dB.ldev (7.0 MB)
