Question

The circuit shown below is a primitive version of an analog to digital converter, ADC. You should be famiiar with its individual components such as the TTL 74193 4 bit up/down counter and the 3 op-amp configurations. (All op-amps are ideal. The TTL outputs of the 74193 are either 0 or 5V.) Study each component and try to understand its function. Hint the lUP /DOWN input of the 74193 makes the counter count up for a LO input and down for a HI input) 74193가 My .ko Q2 40 k2 LSB 80 ㏀ 5 VDC Q0 UP/DOWN NA kHz CLK Analog Vin Determine which two (decimal) values will the 74193 counter ultimately hover around when the analog input voltage, Vin, is 2.1V? Lower Value: Upper Value:
