Delay for the T section is given by ________(a) ts = ^1⁄fc(b) ts = 1(c) ts = ^1⁄π(d) ts = ^1⁄πfcThis question was posed to me in unit test.This interesting question is from Delay Line topic in division Oscilloscopes of Electrical Measurements

Answer»

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.
