Question 2 An analog signal with a power Pm-GW, and a bandwidth of 4kHz is sampled at a rate f, = 10ksamples/sec. (a) What value of A will lead to an SQNR of 55dB if uniform quantization is used? (b) If the peak voltage of m(t) is 8V, what value of L satisfies (a)? (c) How many bits per sample should be used? (d) What is the bit rate if we use the number of bits per sample from (c)?...
You are given an analog-to-digital converter (ADC) which is used to convert an input analog signal to a digital signal. The highest frequency present in the input analog signal is 20 Hz. The ADC samples the input analog signal at 1.25 times the minimum required sampling rate. (Note; this ADC “over-samples” the analog input signal; the sampling rate of this ADC is higher than the minimum required sampling rate. The ADC samples at 1.25 times the minimum required sampling rate)....

answer question(c) only
(7.5%) When causal filters are used in real-time signal processing, the output signal always lags the input signal. If the signal is recorded for later off-line filtering, then one simple appronch to eliminate this lag problem is: (i) filter the signal and record its response;) filter the recorded response backwards using the same filter; and (iii) store the resulting response backwards. Let the filter be a causal single pole filter 4. 0
