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

Answer 1

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.
