Delay for the T section is given by ________ A. ts = ^1⁄fc B.

Question

Delay for the T section is given by ________ A. ts = ^1⁄fc B. ts = 1 C. ts = ^1⁄π D. ts = ^1⁄πfc This question was posed to me in unit test. This interesting question is from Delay Line topic in division Oscilloscopes of Electrical Measurements

Right choice is D. ts = ^1⁄πfc The explanation: In the T section of the lumped parameter delay in a delay line circuit of the CRO the delay is given by the relation ts = ^1⁄πfc ts = delay for a single circuit td = total delay n = number of T sections.
