What is the Block diagram of ramp type dvm?

A block diagram of a ramp type Digital Voltmeter (DVM) typically consists of several key components: an input signal conditioning circuit, a ramp generator, an analog-to-digital converter (ADC), and a display unit. The input signal conditioning circuit prepares the voltage signal for measurement. The ramp generator produces a linear voltage ramp that is compared with the input signal, and the ADC converts the time duration of the ramp until it matches the input voltage into a digital value. Finally, the display unit shows the digital representation of the measured voltage.
