# A 3 1/2 digit, rectifier type digital meter is set to read in its 2000 V range. A symmetrical square wave of frequency 50 Hz and amplitude ±100 V is measured using the meter. The meter will read _____

$3\frac{1}{2}$

## Answer (Detailed Solution Below) 111

Given that:

Vin

V_{in} Passes through full-wave Bridge Rectifier

Output of FWBR

Given to Dual slope integrating ADC which measures the average value of the output of FWBR

**\ Reading = 100 ´ 1.11 = 111 (Reading on 2000 Voltage range).**

__Important Points__

A 3.5 digit display is actually four segments, one-half digit, and 3 full digits. Displaying maximum capability it would read 1999.
