A 10 1/2 digit timer counter possesses a base clock of frequency 100 MHz. When measuring a particular input, the reading obtained is the same in: (i) Frequency mode of operation with a gating time of one second and (ii) Period mode of operation (in the x 10 ns scale). The frequency of the unknown input (reading obtained) in Hz is ___________.

A  digit DMM has the error specification as: 0.2% of reading + 10 counts. If a dc voltage of 100V is read on its 200V full scale, the maximum error that can be expected in the reading is

An average-reading digital multi meter reads 10V when fed with a triangular wave, symmetric about the time-axis. For the same input an rms-reading meter will read
